23.1 Introduction

This chapter takes up the working hours provisions of the Factories Act, 1948 in Chapter VI, supplemented by the annual leave provisions in Chapter VIII. The working hours framework is one of the oldest substantive areas of the Act, tracing its lineage to the nineteenth-century campaigns for the limitation of the working day. The contemporary Indian framework reflects both the historical international movement for an eight-hour day and the specific Indian compromises adopted in 1948.

23.2 Weekly Hours and Weekly Holiday (Sections 51 and 52)

Section 51: Weekly Hours

“No adult worker shall be required or allowed to work in a factory for more than forty-eight hours in any week.”

The 48-hour weekly limit is the foundational restriction on working hours under the Act. The limit applies to all adult workers (18 years and above) and is supplemented by the daily limit in Section 54 and the spread-over limit in Section 56.

Section 52: Weekly Holidays

“No adult worker shall be required or allowed to work in a factory on the first day of the week (hereinafter referred to as the said day), unless:

he has or will have a holiday for a whole day on one of the three days immediately before or after the said day, and
the manager of the factory has, before the said day or the substituted day under (i), whichever is earlier:

delivered a notice at the office of the Inspector of his intention to require the worker to work on the said day and of the day which is to be substituted, and
displayed a notice to that effect in the factory.”

The Section provides for a weekly holiday on Sunday by default but permits substitution within a three-day window subject to notice requirements. The substitution mechanism allows continuous-process industries to operate on Sundays with workers receiving a substitute day off.

Section 53 supplements Section 52 by providing for compensatory holidays where a worker is deprived of any of the weekly holidays prescribed under Section 52.

23.3 Daily Hours, Intervals, and Spread-Over (Sections 54, 55, and 56)

Section 54: Daily Hours

“Subject to the provisions of section 51, no adult worker shall be required or allowed to work in a factory for more than nine hours in any day:

Provided that, subject to the previous approval of the Chief Inspector, the daily maximum specified in this section may be exceeded in order to facilitate the change of shifts.”

The 9-hour daily limit, combined with the 48-hour weekly limit, supports a typical pattern of six 8-hour days or five 9.5-hour days (with appropriate intervals).

Section 55: Intervals for Rest

“The periods of work of adult workers in a factory each day shall be so fixed that no period shall exceed five hours and that no worker shall work for more than five hours before he has had an interval for rest of at least half an hour.”

The interval requirement ensures that a worker has a meaningful break after every 5 hours of continuous work. The 30-minute minimum is a floor; many factories provide longer intervals for lunch and shorter intervals for tea or refreshment.

Section 56: Spread-Over

“The periods of work of an adult worker in a factory shall be so arranged that inclusive of his intervals for rest under section 55, they shall not spread over more than ten and a half hours in any day:

Provided that the Chief Inspector may, for reasons to be specified in writing, increase the spread-over up to twelve hours.”

The spread-over limit prevents excessive elongation of the working day through long rest intervals. A worker cannot be required to be at the factory for more than 10.5 hours from start to finish in a day, even if the actual work hours are within the daily limit.

23.4 Night Shifts (Section 57)

Section 57: Night Shifts

Where a worker in a factory works on a shift that extends beyond midnight:

for the purposes of Sections 52 and 53, a holiday for a whole day shall mean a period of twenty-four consecutive hours beginning when his shift ends;
the following day for him shall be deemed to be the period of twenty-four hours beginning when such shift ends, and the hours he has worked after midnight shall be counted in the previous day.

The Section operationalises the application of weekly holidays and daily limits to shift patterns that cross the midnight boundary, ensuring that the day boundaries follow the worker’s shift rather than the calendar.

23.5 Overtime (Section 59)

Section 59: Extra Wages for Overtime

“Where a worker works in a factory for more than nine hours in any day or for more than forty-eight hours in any week, he shall, in respect of overtime work, be entitled to wages at the rate of twice his ordinary rate of wages.

For the purposes of sub-section (1), ‘ordinary rate of wages’ means the basic wages plus such allowances, including the cash equivalent of the advantage accruing through the concessional sale to workers of foodgrains and other articles, as the worker is for the time being entitled to, but does not include a bonus and wages for overtime work.”

The Section establishes the principle of double-rate compensation for overtime. The 2x multiplier is among the highest in international comparison and reflects the legislative judgment that overtime should be exceptional, with the cost falling heavily on the employer who chooses to require it.

State rules typically prescribe a quarterly overtime cap (commonly 50 hours per worker per quarter, with variation across States and industries) to prevent excessive overtime even at the higher rate.

Overtime Computation Is a Frequent Source of Disputes

A practitioner observation worth emphasising is that overtime computation is a frequent source of industrial disputes. The exclusion of “bonus” from the ordinary rate, the inclusion of certain allowances, and the calculation of overtime hours when partial days are worked all raise practical questions. The standard practice is to maintain detailed working hour records and to compute overtime payments transparently, with worker representatives able to verify the calculation.

23.6 Employment of Women (Section 66)

Section 66: Further Restrictions on Employment of Women

“(1) The provisions of this Chapter shall, in their application to women in factories, be supplemented by the following further restrictions, namely:

no exemption from the provisions of section 54 may be granted in respect of any woman;
no woman shall be required or allowed to work in any factory except between the hours of 6 A.M. and 7 P.M.:

Provided that the State Government may, by notification in the Official Gazette, in respect of any factory or group or class or description of factories, vary the limits laid down in clause (b), but no such variation shall authorise the employment of any woman between the hours of 10 P.M. and 5 A.M.

there shall be no change of shifts except after a weekly holiday or any other holiday.”

The Section 66 prohibition on employment of women between 7 p.m. and 6 a.m. has been substantially modified by State-specific notifications and amendments since the early 2000s, permitting night work for women in industries such as IT-enabled services, manufacturing, and pharmaceuticals, subject to specified safeguards. The standard safeguards include:

consent of the worker to night work;
provision of safe transport between residence and workplace;
provision of adequate security at the workplace during night shifts;
provision of facilities (rest rooms, canteens, washrooms) appropriate to night working;
constitution of complaints committees under the Sexual Harassment of Women at Workplace (Prevention, Prohibition and Redressal) Act, 2013.

The Code on Wages, 2019 and the OSH Code, 2020 are expected to further harmonise the position on employment of women, with the trajectory being towards more permissive provisions subject to substantive safeguards.

23.7 Annual Leave with Wages (Chapter VIII)

Chapter VIII of the Factories Act, 1948 provides for annual leave with wages for workers who have worked a minimum period in the preceding year.

Section 79: Annual Leave with Wages

“Every worker who has worked for a period of 240 days or more in a factory during a calendar year shall be allowed during the subsequent calendar year, leave with wages for a number of days calculated at the rate of:

if an adult, one day for every twenty days of work performed by him during the previous calendar year;
if a child, one day for every fifteen days of work performed by him during the previous calendar year.”

The Section produces a typical entitlement of approximately 12 days of annual leave for an adult worker who has worked the standard 240+ days. The leave can be carried forward to a maximum of 30 days for adults and 40 days for children (now adolescents under contemporary law).

Sections 80 to 84 supplement Section 79 by providing for the wages payable during leave (at the rate prevailing in the month preceding the commencement of the leave), the application for leave (typically at least 15 days in advance), the encashment of leave (where the worker quits or is discharged), and the maintenance of a leave register.

23.8 Case Studies

23.8.1 Case Study 1: A Continuous-Process Plant and the Weekly Holiday

A petrochemical plant operates as a continuous process and cannot be shut down for weekly holidays. The plant employs three rotating shifts of workers, each shift covering eight hours. The plant manager designs a roster in which each worker has Sunday off in some weeks and another day off in other weeks, with appropriate notice given to the Inspectorate and the workers.

The arrangement complies with Section 52 if the substituted holiday falls within the three-day window before or after the relevant Sunday and the notice requirements are satisfied. The arrangement also complies with Section 51 if the weekly hours per worker do not exceed 48, and with Section 54 if the daily hours do not exceed 9 (8 plus changeover). The roster must be communicated in writing and displayed in the factory.

Discussion Questions

To what extent should the employer’s discretion in designing rosters for continuous-process plants be balanced with worker preferences?
How should the changeover periods between shifts be treated for the purposes of Section 54 and Section 56?
What lessons does the case offer for the design of working hour patterns in other continuous-process industries?

23.8.2 Case Study 2: An IT-Enabled Service Centre and the Employment of Women

A business process outsourcing centre operates 24x7 to serve global clients across time zones. Approximately 60 per cent of the workforce is women. The centre relies on the State-specific notification permitting employment of women on night shifts subject to safeguards.

The safeguards in place include opt-in consent of each woman worker to night shifts; provision of company-coordinated transport between residence and workplace; deployment of female security personnel at the workplace during night shifts; provision of dedicated rest rooms, canteen access, and washrooms appropriate to night working; functional internal complaints committee under the Sexual Harassment of Women at Workplace Act, 2013; and a worker grievance procedure with escalation to senior management.

Discussion Questions

How should the centre design its night-shift policies to balance operational requirements with worker safety and welfare?
What features of the Sexual Harassment Act compliance interact with the night-shift safeguards under State-specific notifications?
To what extent does the contemporary IT-enabled services context warrant a complete reconsideration of the historical Section 66 framework?

23.8.3 Case Study 3: An Overtime Dispute

A manufacturing facility has a busy quarter and requires substantial overtime work. After the quarter, several workers contest the overtime computation, contending that certain allowances should have been included in the “ordinary rate” base under Section 59, and that the quarterly overtime cap was breached for some workers.

The factory’s HR function reviews the disputes. The Section 59 base for overtime computation includes basic wages plus allowances (including the concessional sale of foodgrains) but excludes bonus and the overtime payments themselves. The factory recomputes the overtime payments, includes some additional allowances, and pays the differences. The breach of the State-specific quarterly cap is addressed by paying the overtime due plus a one-time additional sum, with a commitment to revise scheduling practices to avoid future breaches.

Discussion Questions

To what extent should the overtime cap be respected as a rigid limit, even where business circumstances would otherwise warrant higher overtime?
How should the factory design its working hour planning to minimise the risk of overtime cap breaches?
What lessons does the case offer for the integration of working hour compliance into broader operational planning?
