Case Study

How a plant opened a night shift to women

Its assembly floor was mostly women and its new night shift could not be. What the site changed before the first roster ran, and what it took.

An electronics assembly operation in Tamil Nadu needed a third shift, and about two-thirds of the people who could actually do the work were women it had never rostered after 7 p.m. The law was not the obstacle. The condition set was, and most of it was lighting, transport and paperwork rather than anything structural. The night line ran at strength in the eleventh week. This is a representative composite; no single client is described.

The situation

~430workers across two shifts, direct and contract [VERIFY: composite figure]
~64%of the assembly and inspection crew were women [VERIFY: composite figure]
0women rostered after 7 p.m. before the project [VERIFY: composite figure]
~11 weeksfrom decision to the first full night roster [VERIFY: composite figure]

The site assembled and tested electronic sub-assemblies on two shifts, with the assembly, inspection and packing stations largely staffed by a contract workforce and the machine-tending and stores roles largely by direct employees. A new order needed a third shift. On paper that is a recruitment problem; in practice the plant had trained its assembly and inspection skill into a crew that was about two-thirds women, and it had never rostered a woman past 7 p.m. Building a night crew out of the remaining third meant either training men into inspection from scratch or running the night line below strength.

The plant's own understanding of why was wrong in a specific and common way. Its HR head believed a state exemption had to be applied for, and that a night shift needed at least ten women before it could run at all. Neither describes the position under the Code. Section 43 of the OSH Code 2020 entitles women to be employed in all establishments for all types of work, and to work before 6 a.m. and beyond 7 p.m. with their consent, subject to conditions prescribed in the rules. There is no application to make. What there is, is a list to satisfy, and nobody had ever read the list against this particular site.

The commercial case did not need much arithmetic. Female labour force participation for persons aged 15 and above was 40.0% in 2025 against 79.1% for men, on the Periodic Labour Force Survey annual report. A site that has already attracted, trained and retained a majority-women crew on its most skill-dependent stations is holding something scarce, and a shift pattern that locks that crew out after 7 p.m. is not a staffing constraint so much as a self-imposed one.

What the 11 p.m. walk found

We walked the route a woman would actually take, at the hour she would take it, before writing anything down. A daytime inspection passes almost every site; the rules describe a route after dark, so the audit has to happen after dark. Two people walked from the gate to each night workstation, then from each workstation to the toilet block, the drinking water point and back, at around 11 p.m. on an ordinary working night.

What we checkedWhat we foundWhat the rules require
ConsentTaken verbally by the line supervisor and ticked in a registerConsent of the woman employee, in writing under the Central Rules (r.83(a)); the Tamil Nadu draft requires consent without specifying writing (r.42(1))
TransportA drop at three points on the main road; the last stretch walked, in one case about 1.5 kmAdequate transport to pick up and drop her at her residence (r.83(c); draft r.42(3))
Lighting on the floorAdequate at every workstationWorkplace to be well-lit (r.83(d); draft r.42(4))
Lighting on the routeTwo of five fittings out along the passage from packing to the women's toilet block, which went dark when the day shift's lights were switched off at the panelThe passage towards toilet, washroom, drinking water, entry and exit to be well-lit (r.83(d); draft r.42(4))
Distance to facilitiesThe women's toilet block sat across the yard from the night workstations, roughly twice the walk of the men'sToilet, washroom and drinking water near the workplace (r.83(d); draft r.42(5))
Sanitary provisionVending unit present and empty; no lidded bins; disposal by the general waste routeNapkins to BIS standards, free and replenished daily, lidded bins, disposal by electrical incinerator (draft r.42(6), (7))
Emergency numbersDisplayed at the security desk onlyDedicated numbers displayed at the establishment and inside the vehicles (r.83(f))
Camera coverageGate and production hall covered; the walkway to the facilities was notSuitable CCTV surveillance on the way to those facilities (r.83(d)); not required by the Tamil Nadu draft
POSHInternal Committee constituted, but the contract crew had not been told it existed and no member sat on the night shiftCompliance with the Sexual Harassment of Women at Workplace Act 2013 as applicable (r.83(h); draft r.42(9))
CrècheNever tested against total headcountCrèche where fifty or more employees are ordinarily employed, within one kilometre, for children under six (Code on Social Security 2020, s.67; Social Security (Central) Rules 2026, r.37)

Nothing on that list is exotic, and none of it was discovered by reading a policy document. The lighting failure existed only after the day shift ended, because the panel that killed the day lights also killed half the passage. The transport failure existed only for the workers who lived off the three main-road points. Both are invisible at 3 p.m.

What we did

The work split cleanly into things the site had to fix because they are fixed to the premises, and things the contractor had to fix because they attach to the employment. That split is not a matter of preference. Section 53 of the OSH Code provides that the welfare facilities specified under sections 23 and 24 are to be provided by the principal employer of the establishment to the contract labour employed there, and lighting, drinking water, latrines and washing facilities are section 23 and 24 items. A contractor cannot relight a client's passage.

  • Re-lamped and re-circuited the route, then re-walked it. The passage, the yard crossing and the entry and exit were put on the night panel rather than the day one, the dead fittings replaced, and the walk repeated at 11 p.m. with the night electrician present. This was the site's work, not the contractor's.
  • Moved the facilities to the crew rather than the crew to the facilities. Rather than rebuild a toilet block, the night stations were relocated to the hall nearest the existing women's facilities. Reading the rule as a distance requirement made the cheap answer obvious.
  • Sanitary provision put on the housekeeping round. Stocked to BIS-standard product, replenished daily as a checklist item rather than on request, lidded bins installed, and disposal moved off the general waste route.
  • Consent rewritten and re-taken, in writing, per worker. Held by the contractor as the employer of the contract crew, copied to the site, and renewed when a worker moved between shifts rather than treated as a one-time signature. The Central Rules require writing; the Tamil Nadu draft does not say so, and writing is the version that can be produced later.
  • Transport re-routed to residences, with the numbers inside the vehicle. Two routes replaced three fixed points, the drop moved to the residence, and the dedicated emergency numbers were displayed inside each vehicle as well as on the floor. Who books and who pays was written into the work order instead of being assumed.
  • Camera coverage extended to the walkway. The existing system reached the gate and the line; the gap was the route to the facilities, which is precisely where the Central rule points.
  • POSH made real on the night shift. The Internal Committee's existence, membership and how to reach it were put in front of the contract crew in Tamil, and the committee's composition was revisited so that a worker on nights had someone reachable. Which committee a contract worker complains to is settled by the 2013 Act rather than by the OSH rules, so the contract was made explicit about it.
  • Crèche threshold actually tested. Counted against total headcount ordinarily employed rather than direct payroll alone, which is the reading the site had never applied [VERIFY: whether contract workers count toward the s.67 threshold on these facts was referred to the site's counsel, not resolved by us].

What changed

The night line ran at full strength from the eleventh week, staffed from the existing trained crew rather than from a new intake. The recruitment problem the site thought it had did not need solving: the people were already on site and already trained, and what had excluded them was a lighting circuit, a bus route and a consent form.

The part worth carrying to another site is the order of operations. The legal question, which is the one everybody starts with, took an afternoon to answer and was not the constraint. The condition set took eleven weeks, and more than half of that was lighting and transport, which no policy review would have surfaced because both were fine in daylight. The site now repeats the 11 p.m. walk once a quarter and after any change to the lighting panel, and treats it as a night-shift equivalent of a safety round.

Whether any particular arrangement satisfies a particular site's obligations, and how rule 84B(6) applies after the repeal, are questions for that site's own counsel and the Labour Department. This composite describes a sequence of work, not a compliance opinion and not a guarantee.

Frequently asked questions

Does a factory need government permission to put women on a night shift?

Not under the OSH Code 2020. Section 43 entitles women to be employed in all establishments for all types of work, and before 6 a.m. and beyond 7 p.m. with their consent, subject to conditions prescribed in the rules. There is no exemption application in that scheme. The work is meeting the conditions — consent, transport, lighting, nearby facilities and POSH compliance — not obtaining a permission.

What usually fails when a site is audited for a women's night shift?

Lighting and transport, in our experience, because both look fine during the day. The route to the toilets and drinking water often runs off the day-shift lighting panel and goes dark when that panel is switched off, and transport frequently stops at fixed points on a main road rather than at the worker's residence, which is what the rule actually requires. Both are found by walking the route at the hour it will be walked.

Who fixes what when the night crew is contract labour?

Anything fixed to the premises is the site's. Section 53 of the OSH Code provides that the welfare facilities under sections 23 and 24, which include lighting, drinking water, latrines and washing facilities, are provided by the principal employer to contract labour employed in the establishment. Consent and transport attach to the employer of the worker. A contractor cannot relight a client's passage, and a work order that assumes otherwise will not hold.

Is the old Tamil Nadu ten-women rule still in force?

It is unsettled. Rule 84B(6) of the Tamil Nadu Factories Rules 1950 set a minimum of ten women per night shift, two-thirds of shift strength and one-third of supervisors. The Factories Act 1948 was repealed when the OSH Code commenced on 21 November 2025, though section 143(3) keeps rules made under repealed Acts in force so far as they are not contrary to the Code. Neither the Central Rules nor the Tamil Nadu draft carries a minimum. Ask your own counsel.
