Social Dialogue for Effective Industrial Relations

Published

Shares

Each enterprise has a history of industrial relations and knowledge of the history facilitates in developing enterprise specific strategy for an effective industrial relations climate in the present and the future.

We are well conversant with John T Dunlop’s "System Model", which considered Industrial Relations as a subsystem of society, distinct from, but overlapping other subsystems. He suggested that Industrial Relations system could be divided into four interrelated elements comprising of certain actors, certain context, an ideology which binds the industrial relations system together and a body of rules created to govern the actors at the workplace.

Each enterprise has a history of industrial relations and knowledge of the history facilitates in developing enterprise specific strategy for an effective industrial relations climate in the present and the future. Industrial relations in an enterprise, is also dependent upon the organisation’s culture, governance practices, style of management of the owners/top management as well as the approach and style of functioning of the union/s and the methods deployed by them for handling of industrial relations issues of the organisation. Industrial relations in an enterprise is dependent on applicable relevant labour laws, contract of employment, rules and regulations of the enterprise, as well as past agreements between the management and the trade union that are supposed to be complied with by both management and trade unions.

At times there are differences in approach between managements and trade unions on the methodology to be adopted on resolution of disputes, which at times do create industrial relation problems. Industrial relations issues in an enterprise can be on various issues some of which are recognition of union/s, aspects of work, terms and conditions of employment, compensation, welfare measures, promotion policy, rewards, and punishments arising out of disciplinary proceedings. Both the management and the trade union of an enterprise need to have an approach on finding solutions to the problems, while maintaining discipline, improved quality, and improved productivity coupled with uninterrupted operations and continuity of growth of the enterprise and development of the workforce. Hence, an effective communication involving social dialogue from both management and union does act as a catalyst in building an effective industrial relations climate.

Industrial relations climate is enterprise specific; the industrial relations climate differs from one enterprise to another and from one region to the other, depending upon the attitude and behaviour of the top management towards trade union and of trade union towards top management and also amongst the trade unions.

The ratio of permanent workers to contract workers over a period of time has become skewed; earlier i.e. till 1990s, there used to be higher number of permanent workers than the contract workers. In the decade of 1991 to 2000 the number of above two types of workforce changed drastically, which did gave rise to series of litigation concerning permanency, equal pay for equal work etc. i.e. contract workers desiring parity with the permanent workers. Beyond 2000, the number of contract workers has surpassed the number of permanent workers in many enterprises. Presently large number of enterprises are engaging substantial number of contract workers at the workplace, both in the manufacturing and the service sector, hence wage and service conditions of contract workers working for an enterprise is becoming a major issue for trade unions and workers, hence this is bound to continue to have Industrial Relations implications.

The areas of labour legislation impacting industrial relations in India are governed by The Trade Union Act, 1926, The Industrial Employment [Standing Orders] Act, 1946, The Payment of Wages Act, 1936, The Minimum Wages Act, 1948, The Payment of Bonus Act, 1965, The Equal Remuneration Act, 1976, The Industrial Disputes Act, 1947 and The Contract Labour (Regulation & Abolition) Act, 1970 apart from certain state legislations applicable to certain States of India.

The present National Democratic Alliance (NDA) Government, under the Ministry of Labour and Employment, has looked at clubbing (i) Laws governing wages by consolidating: The Minimum Wages Act, 1948, The Payment of Wages Act, 1936, The Payment of Bonus Act, 1965 and The Equal Remuneration Act, 1976 under Labour Code on Wages Bill, 2017 and (ii) Laws governing terms and conditions of employment by consolidating: Trade Unions Act, 1926, Industrial Employment [Standing Orders] Act, 1946 and Industrial Disputes Act, 1947 under Labour Code on Industrial Relations Bill, 2015. The conversion of these present Acts into two Codes will lead to a commonality of definition under each of the Codes, but the contents of the existing laws have been copied under the Code, with hardly any change in the content of the Acts incorporated in the Code. These two new codes will be the new labour legislations impacting Industrial Relations in India, once they become laws.

ILO convention No. 144 on social dialogue
The ILO is moving towards its centenary in 2019, and the ILO Office has stepped up its efforts to encourage universal ratification of ILO Convention No. 144 passed in 1976 dealing with Tripartite Consultation also referred to as Social Dialogue. The ILO Declaration on Social Justice for a Fair Globalisation, adopted unanimously at the International Labour Conference in 2008, identified this convention as one of the four most significant instruments from the viewpoint of governance.

ILO has been propagating "Social Dialogue" at the international, national and enterprise level with an objective of finding solution to problems and hence developed ILO Convention No. 144 dealing with "Social Dialogue" which was ratified by India in 1978.

The ILO definition on "Social Dialogue" is ‘All types of negotiations, consultation or simply exchange of information between or amongst representatives of governments, employers and workers on issues of common interest to economic and social policy’. This ILO Convention No. 144 dealing with Social Dialogue is an approach at finding solutions to problems and hence the International Labour Organization does propagate this convention to the Governments, Employer Organizations and Trade Unions of each member coutry, so as to improve the climate for effective Industrial Relations.

Employment model post 1991
In India post 1991, majority of the enterprises in the manufacturing as well as service sector undertook voluntary retirement schemes and heavily reduced the unionised workforce; hence the industrial relations climate in enterprises has gone through a major change, as unionised work force in the formal sector, who were employees of the enterprise and members of trade unions, fell drastically. These enterprises in the future limited the employment of unionised workforce and met future requirement of workforce by and large, through recruitment of employees in the management cadre, and in quite many case by obtaining contract work force through a contractor / service provider or outsourced quite a few activities.

Enterprises born post 1991, both in the manufacturing and service sector have built an employment model wherein maximum employees are in the management cadre; few employees are in the worker category. Enterprises engage a substantial number of contract workers, who work for the enterprise through a contractor/service provider and their working for the enterprise are governed by the The Contract Labour (Regulation & Abolition) Act, 1970.

This employment model has brought in new dimensions in Industrial Relations wherein the enterprise claim that the contract workers are employees of the contractor and not of the enterprise, though they continue to work for the enterprise , through the contractor / service provider for many years. In certain enterprises break in service is given to these contract workers through the contractor/service provider, who transfers their service to another enterprise or terminates their employment periodically. Presently there are many contractors/service providers supplying large number of workforce to enterprises. Some of these contractors employ more than 30,000 workers and supply contract labour to various enterprises.

Human resource development initiatives
Post 1991, enterprises in India have undertaken various human resource development initiatives for employees that belong to the management cadre. For an effective and conducive industrial relations climate there are enterprises that have undertaken human resource development initiative/activity, which impacts the workers in the enterprise, who could be or are members of a trade union. Very few enterprises extend these human resource development initiative/activity to contract workers engaged by the enterprise, as these workers are employees of the contractor/service provider and not of the enterprise where they work.

In a training programme on "Improving Industrial Relations" conducted by me for an enterprise, I was explaining ILO Convention No. 144 dealing with Social Dialogue to the participants. I conducted a brainstorming exercise with the participants and they evolved a list of Human Resource Initiative / Engagement Activity that can be undertaken by the enterprise for improved communication and building a conducive and positive work culture. The list that emerged is by and large the type of initiatives that most enterprises presently undertake. I then divided the participants which comprised of management personnel and internal trade union leaders to form groups of management team and trade union team and then look at each of the Human Resource Initiative / Activity and identify the perception of benefit to the Management and perception of benefits to the Trade Union / Workers. The result that emerged in the exercise is given in the table.

The perceptions that emerged during the exercise was to make both the management and trade union participants understand each other’s perspective, and the need to have social dialogue with an objective of building a conducive and effective industrial relations climate in the enterprise and building a culture of collaboration rather than confrontation.

These human resource development initiatives/engagement activities are long term in nature.

It cannot do a magic to change the union-management relationship in a short period. It needs involvement of the entire workforce at the site plus their unions. It takes a lot of time for the union-management relationship to mature and be institutionalised where both sides trust each other. The principle of trust is that trust is built on trust and never on mistrust.

A conducive and effective Industrial Relations climate can facilitate in avoiding a culture which could lead to strikes / lockouts, as they are expensive remedies for both sides.

Conclusion
In India post 1991, the employment model in most enterprises has changed and the engagement of contract workers through contractors/service providers both in manufacturing and service sector enterprises is not marginal but substantially high. In quite many enterprises the contract workers working is more than the total permanent employees (management staff plus permanent workers).

The labour codes drafted by the present National Democratic Alliance (NDA) Government under the Ministry of Labour & Employment have still not dealt with the issue of Contract Labour which is covered under The Contract Labour (Regulation & Abolition) Act, 1970. To reduce litigation / dispute on contract labour there is a need to define core and noncore jobs and defining areas of engagement of contract labour and permanent employees by Government of India. Andhra Pradesh Government under the Rules of Andhra Pradesh dealing with The Contract Labour (Regulation & Abolition) Act, 1970 permits engagement of contract labour only in defined noncore jobs. This has helped in ensuring that contract labour is not engaged in core jobs of an enterprise and the same are carried out by permanent workers.

In majority of the enterprises in India the contract workers are engaged in noncore and core jobs, paid only the statutory minimum wages or marginally higher, while they continue to serve the enterprise for years, just like permanent employees (management staff plus permanent workers). In most cases, the contract workers do not enjoy benefits of any annual rise in wages like the permanent employees (management staff plus permanent workers) or the long term settlement benefits received by permanent workers. There is a need for social dialogue between management and unions and work on a constructive approach, as employers/top management desire flexibility linked to business needs, as a step towards ease of doing business; at the same time the unions desire reasonable remuneration plus a safety net, when they lose employment, because of the employers decision to restructure workforce based on business needs.

This present business model on contract workers being paid minimum wages along with negligible security of employment is bound to lead to industrial relations issues when this workforce compares its remuneration and working conditions with the employees who are directly employed by the enterprise. There is need for managements and trade unions to find solutions to the problem of contract workers through social dialogue at the enterprise level, otherwise this will one day lead to reemergence of unpleasant Industrial Relations climate at enterprise levels, similar to those that we witnessed in the 1960’s, 1970’s and 1980’s in certain parts of India.

Digital process control is transforming grinding

Published

Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, delves into how digital intelligence is transforming cement grinding into a predictive, stable, and energy-efficient operation.

Grinding sits at the heart of cement manufacturing, accounting for the largest share of electrical energy consumption. In this interview, Satish Maheshwari, Chief Manufacturing Officer, Shree Cement, explains how advanced grinding technologies, data-driven optimisation and process intelligence are transforming mill performance, reducing power consumption and supporting the industry’s decarbonisation goals.

How has the grinding process evolved in Indian cement plants to meet rising efficiency and sustainability expectations?
Over the past decade, Indian cement plants have seen a clear evolution in grinding technology, moving from conventional open-circuit ball mills to high-efficiency closed-circuit systems, Roller Press–Ball Mill combinations and Vertical Roller Mills (VRMs). This shift has been supported by advances in separator design, improved wear-resistant materials, and the growing use of digital process automation. As a result, grinding units today operate as highly controlled manufacturing systems where real-time data, process intelligence and efficient separation work together to deliver stable and predictable performance.
From a sustainability perspective, these developments directly reduce specific power consumption, improve equipment reliability and lower the carbon footprint per tonne of cement produced.

How critical is grinding optimisation in reducing specific power consumption across ball mills and VRMs?
Grinding is the largest consumer of electrical energy in a cement plant, which makes optimisation one of the most effective levers for improving energy efficiency. In ball mill systems, optimisation through correct media selection, charge design, diaphragm configuration, ventilation management and separator tuning can typically deliver power savings of 5 per cent to 8 per cent. In VRMs, fine-tuning airflow balance, grinding pressure, nozzle ring settings, and circulating load can unlock energy reductions in the range of 8 per cent to 12 per cent. Across both systems, sustained operation under stable conditions is critical. Consistency in mill loading and operating parameters improves quality control, reduces wear, and enables long-term energy efficiency, making stability a key operational KPI.

What challenges arise in maintaining consistent cement quality when using alternative raw materials and blended compositions?
The increased use of alternative raw materials and supplementary cementitious materials (SCM) introduces variability in chemistry, moisture, hardness, and loss on ignition. This variability makes it more challenging to maintain consistent fineness, particle size distribution, throughput and downstream performance parameters such as setting time, strength development and workability.
As clinker substitution levels rise, grinding precision becomes increasingly important. Even small improvements in consistency enable higher SCM utilisation without compromising cement performance.
Addressing these challenges requires stronger feed homogenisation, real-time quality monitoring and dynamic adjustment of grinding parameters so that output quality remains stable despite changing input characteristics.

How is digital process control changing the way grinding performance is optimised?
Digital process control is transforming grinding from an operator-dependent activity into a predictive, model-driven operation. Technologies such as online particle size and residue analysers, AI-based optimisation platforms, digital twins for VRMs and Roller Press systems, and advanced process control solutions are redefining how performance is managed.
At the same time, workforce roles are evolving. Operators are increasingly focused on interpreting data trends through digital dashboards and responding proactively rather than relying on manual interventions. Together, these tools improve mill stability, enable faster response to disturbances, maintain consistent fineness, and reduce specific energy consumption while minimising manual effort.

How do you see grinding technologies supporting the industry’s low-clinker and decarbonisation goals?
Modern grinding technologies are central to the industry’s decarbonisation efforts. They enable higher incorporation of SCMs such as fly ash, slag, and limestone, improve particle fineness and reactivity, and reduce overall power consumption. Efficient grinding makes it possible to maintain consistent cement quality at lower clinker factors. Every improvement in energy intensity and particle engineering directly contributes to lower CO2 emissions.
As India moves toward low-carbon construction, precision grinding will remain a foundational capability for delivering sustainable, high-performance cement aligned with national and global climate objectives.

How much potential does grinding optimisation hold for immediate energy
and cost savings?
The potential for near-term savings is substantial. Without major capital investment, most plants can achieve 5 per cent to 15 per cent power reduction through measures such as improving separator efficiency, optimising ventilation, refining media grading, and fine-tuning operating parameters.
With continued capacity expansion across India, advanced optimisation tools will help ensure that productivity gains are not matched by proportional increases in energy demand. Given current power costs, this translates into direct and measurable financial benefits, making grinding optimisation one of the fastest-payback operational initiatives available to cement manufacturers today.

Refractory demands in our kiln have changed

Published

Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, points out why performance, predictability and life-cycle value now matter more than routine replacement in cement kilns.

As Indian cement plants push for higher throughput, increased alternative fuel usage and tighter shutdown cycles, refractory performance in kilns and pyro-processing systems is under growing pressure. In this interview, Radha Singh, Senior Manager (P&Q), Shree Digvijay Cement, shares how refractory demands have evolved on the ground and how smarter digital monitoring is improving kiln stability, uptime and clinker quality.

How have refractory demands changed in your kiln and pyro-processing line over the last five years?
Over the last five years, refractory demands in our kiln and pyro line have changed. Earlier, the focus was mostly on standard grades and routine shutdown-based replacement. But now, because of higher production loads, more alternative fuels and raw materials (AFR) usage and greater temperature variation, the expectation from refractory has increased.
In our own case, the current kiln refractory has already completed around 1.5 years, which itself shows how much more we now rely on materials that can handle thermal shock, alkali attack and coating fluctuations. We have moved towards more stable, high-performance linings so that we don’t have to enter the kiln frequently for repairs.
Overall, the shift has been from just ‘installation and run’ to selecting refractories that give longer life, better coating behaviour and more predictable performance under tougher operating conditions.

What are the biggest refractory challenges in the preheater, calciner and cooler zones?
• Preheater: Coating instability, chloride/sulphur cycles and brick erosion.
• Calciner: AFR firing, thermal shock and alkali infiltration.
• Cooler: Severe abrasion, red-river formation and mechanical stress on linings.
Overall, the biggest challenge is maintaining lining stability under highly variable operating conditions.

How do you evaluate and select refractory partners for long-term performance?
In real plant conditions, we don’t select a refractory partner just by looking at price. First, we see their past performance in similar kilns and whether their material has actually survived our operating conditions. We also check how strong their technical support is during shutdowns, because installation quality matters as much as the material itself.
Another key point is how quickly they respond during breakdowns or hot spots. A good partner should be available on short notice. We also look at their failure analysis capability, whether they can explain why a lining failed and suggest improvements.
On top of this, we review the life they delivered in the last few campaigns, their supply reliability and their willingness to offer plant-specific custom solutions instead of generic grades. Only a partner who supports us throughout the life cycle, which includes selection, installation, monitoring and post-failure analysis, fits our long-term requirement.

Can you share a recent example where better refractory selection improved uptime or clinker quality?
Recently, we upgraded to a high-abrasion basic brick at the kiln outlet. Earlier we had frequent chipping and coating loss. With the new lining, thermal stability improved and the coating became much more stable. As a result, our shutdown interval increased and clinker quality remained more consistent. It had a direct impact on our uptime.

How is increased AFR use affecting refractory behaviour?
Increased AFR use is definitely putting more stress on the refractory. The biggest issue we see daily is the rise in chlorine, alkalis and volatiles, which directly attack the lining, especially in the calciner and kiln inlet. AFR firing is also not as stable as conventional fuel, so we face frequent temperature fluctuations, which cause more thermal shock and small cracks in the lining.
Another real problem is coating instability. Some days the coating builds too fast, other days it suddenly drops, and both conditions impact refractory life. We also notice more dust circulation and buildup inside the calciner whenever the AFR mix changes, which again increases erosion.
Because of these practical issues, we have started relying more on alkali-resistant, low-porosity and better thermal shock–resistant materials to handle the additional stress coming from AFR.

What role does digital monitoring or thermal profiling play in your refractory strategy?
Digital tools like kiln shell scanners, IR imaging and thermal profiling help us detect weakening areas much earlier. This reduces unplanned shutdowns, helps identify hotspots accurately and allows us to replace only the critical sections. Overall, our maintenance has shifted from reactive to predictive, improving lining life significantly.

How do you balance cost, durability and installation speed during refractory shutdowns?
We focus on three points:
• Material quality that suits our thermal profile and chemistry.
• Installation speed, in fast turnarounds, we prefer monolithic.
• Life-cycle cost—the cheapest material is not the most economical. We look at durability, future downtime and total cost of ownership.
This balance ensures reliable performance without unnecessary expenditure.

What refractory or pyro-processing innovations could transform Indian cement operations?
Some promising developments include:
• High-performance, low-porosity and nano-bonded refractories
• Precast modular linings to drastically reduce shutdown time
• AI-driven kiln thermal analytics
• Advanced coating management solutions
• More AFR-compatible refractory mixes

These innovations can significantly improve kiln stability, efficiency and maintenance planning across the industry.
