The Bonus Concept

Why This Matters

A textile mill in Ahmedabad makes a profit of Rs. 2 crore. Workers demand a share. The employer says bonus is a gift, payable at discretion. The workers say it is a right, earned through labour that generated the profit. This dispute shaped Indian labour law for decades. The Full Bench Formula (1950) attempted to resolve it by creating a principled method for computing the employer's obligation. The Payment of Bonus Act, 1965 (now subsumed in the Code on Wages, 2019) converted the judicial formula into statute. This chapter covers the conceptual and historical foundation before Chapter 2.2 covers the statutory scheme.

Chapter Overview

This chapter answers four questions:

1. What is bonus? The competing theories: production bonus, profit sharing, deferred wage, or statutory right.
2. How did the Full Bench Formula work? The Labour Appellate Tribunal's five step computation that preceded the statute.
3. What role did the Bonus Commission play? The 1964 Commission that led directly to the Payment of Bonus Act, 1965.
4. Is there a "right" to bonus? The evolution from ex gratia payment to statutory entitlement.

The Nature of Bonus

This section traces how bonus evolved from a discretionary gift to a statutory right.

Bonus in Indian labour law has been understood through four competing theories. Each theory reflects a different view of the worker's relationship to the employer's profit.

The Production Bonus Theory

Bonus is additional payment for higher productivity. Under this view, bonus rewards workers who produce more than a standard output. It is incentive linked, not profit linked. This theory treats bonus as part of the wage bargain: work harder, earn more.

The limitation of this theory is that it applies only to measurable output. It cannot explain bonus for clerical, administrative, or service sector workers whose output is not quantifiable per unit.

The Profit Sharing Theory

Bonus is the worker's share in the profits generated by their labour. This is the dominant theory in Indian jurisprudence. The logic: profits result from the combined contribution of capital and labour. Capital receives dividends. Labour should receive a share of the surplus beyond the minimum return on capital.

This theory was the foundation of the Full Bench Formula and eventually the Payment of Bonus Act. It ties bonus directly to profitability: no profit, no bonus (beyond the statutory minimum).

The Deferred Wage Theory

Bonus is wages earned but withheld, paid at a later date. Under this view, workers create value throughout the year but receive less than the full value of their labour. Bonus is the deferred portion, payable after accounts are finalised. This theory supports the idea of bonus as a right rather than a discretion.

The Statutory Right Theory

Bonus is a legal entitlement created by statute, independent of any underlying theory. After the Payment of Bonus Act, 1965, the theoretical debate became less significant because the statute prescribes minimum and maximum bonus regardless of which theory one subscribes to. The Act (now Code on Wages) creates the right. The theory explains why.

The Right to Claim Bonus

The right to bonus evolved through three judicial stages before becoming statutory.

Stage 1: Ex gratia (discretionary). Before independence, bonus was entirely at the employer's discretion. Workers had no legal claim. Employers paid bonus as a customary practice during festivals (Diwali, Puja) but could withhold it at will.

Stage 2: Judicially recognised right. In the post independence period, industrial tribunals began recognising bonus as a right linked to profits. The key development was the Full Bench Formula (1950), which provided a principled computation method. Tribunals could order bonus payment as part of industrial dispute adjudication.

Stage 3: Statutory right. The Payment of Bonus Act, 1965, converted the judicially developed right into a statutory entitlement with fixed minimum and maximum percentages. The Act is now subsumed in the Code on Wages, 2019.

The Full Bench Formula

The Full Bench Formula (1950) was the first systematic attempt to compute the employer's bonus obligation. It remained the basis of bonus computation until codified (with modifications) in the Payment of Bonus Act, 1965.

The formula works in five sequential steps:

Step 1: Determine Gross Profits

Calculate the gross profits of the establishment for the accounting year. This is the starting point: the total surplus generated before any prior claims are deducted.

Step 2: Deduct Prior Charges

From gross profits, deduct the following prior charges in order:

• Depreciation admissible under the Income Tax Act
• Reserves for rehabilitation of machinery and plant
• Return on paid up capital at a rate not exceeding 6% (to compensate shareholders)
• Return on working capital used in the business

These prior charges represent the minimum return that capital is entitled to before labour can claim a share.

Step 3: Determine Available Surplus

Gross Profits minus Prior Charges = Available Surplus. This is the pool from which bonus is payable.

Step 4: Allocable Surplus

The entire available surplus is not allocated to bonus. The Payment of Bonus Act (and now the Code) prescribes that 67% of available surplus is allocable surplus in a company (60% in other establishments).

Step 5: Distribute as Bonus

The allocable surplus is distributed as bonus to eligible employees, subject to minimum and maximum limits prescribed by statute.

The Bonus Commission (1964)

The Government of India appointed the Bonus Commission in 1964 to examine the bonus question comprehensively and recommend a permanent statutory framework.

The Commission was necessitated by recurring industrial disputes over bonus computation. The Full Bench Formula provided a framework, but its application varied across tribunals. Employers and unions constantly litigated the quantum of prior charges, the rate of return on capital, and the basis for computing gross profits. A uniform statutory scheme was needed.

Key recommendations of the Bonus Commission:

• Bonus should be a statutory right, not dependent on tribunal adjudication
• Minimum bonus should be payable even in years of loss (to prevent exploitation)
• Maximum bonus should be capped to balance worker entitlement with capital needs
• The Full Bench Formula should be codified with standardised prior charges
• Set on and set off mechanism to smooth bonus across profitable and loss making years

These recommendations were enacted almost verbatim as the Payment of Bonus Act, 1965. The Act has since been subsumed into the Code on Wages, 2019, but the core structure (minimum, maximum, allocable surplus, set on/set off) remains unchanged.

Set On and Set Off

The set on/set off mechanism smooths bonus across years, preventing windfall in good years and zero in bad years.

Illustration: In Year 1, the allocable surplus is Rs. 10 lakh but the maximum bonus payable is Rs. 7 lakh. The excess Rs. 3 lakh is "set on" (carried forward). In Year 2, the allocable surplus is only Rs. 4 lakh but the minimum bonus payable is Rs. 6 lakh. The Rs. 2 lakh deficit is covered by the Rs. 3 lakh set on from Year 1. The remaining Rs. 1 lakh of set on continues to carry forward.

Explain the concept of Bonus

Bonus in Indian labour law has evolved from a discretionary gift to a statutory right. Four theories explain its nature: production bonus (incentive for output), profit sharing (worker's share of surplus), deferred wage (earned but withheld), and statutory right (entitlement created by law). Indian jurisprudence primarily follows the profit sharing theory.

The right to bonus was first judicially recognised in the Mill Owners Association case (1950), where the Labour Appellate Tribunal laid down the Full Bench Formula for computing bonus from surplus profits. The Bonus Commission (1964) recommended a permanent statutory framework, leading to the Payment of Bonus Act, 1965. This Act, now subsumed in the Code on Wages, 2019, prescribes minimum bonus (8.33%) payable even in loss years and maximum bonus (20%), with a set on/set off mechanism to smooth payments across years.

Explain the Full Bench Formula

The Full Bench Formula was laid down by the Labour Appellate Tribunal in Mill Owners Association, Bombay v. Rashtriya Mill Mazdoor Sangh (1950). It computes the employer's bonus obligation in five steps.

Step 1: Determine gross profits for the accounting year. Step 2: Deduct prior charges: depreciation, rehabilitation reserves, return on paid up capital (6%), and return on working capital. Step 3: Gross profits minus prior charges equals available surplus. Step 4: 67% of available surplus (for companies; 60% for others) equals allocable surplus. Step 5: Distribute allocable surplus as bonus to eligible employees.

In Associated Cement Companies (1959), the Supreme Court endorsed the Formula but clarified that prior charges must be genuine, not inflated to defeat workers' claims. The Formula was codified with modifications in the Payment of Bonus Act, 1965.

Part A (6 marks)

Explain Set On and Set Off

The set on/set off mechanism under the Payment of Bonus Act (now Code on Wages) smooths bonus across profitable and loss making years.

Set on applies when the allocable surplus in a year exceeds the maximum bonus payable. The excess is carried forward to compensate a future deficit. Set off applies when the allocable surplus falls short of the minimum bonus payable. The deficit is carried forward to be adjusted against future surplus.

Both carry forward for a maximum of four years, after which they lapse. The mechanism ensures workers receive minimum bonus even in lean years (funded from past surpluses) and prevents windfall in exceptionally profitable years (excess saved for future shortfalls).
