Calculate comp off (compensatory leave) — the day-in-lieu for working weekly offs and holidays: how policies credit it (full/half-day thresholds), typical 30-90 day expiry windows, and when lapsed comp offs must convert to overtime pay.
Quick answer: Comp off = a substitute paid day for working your weekly off/holiday. For Factories Act and shops-act covered workers a substitute rest day is a statutory right (plus OT rates where hours exceed limits); for exempt/IT staff it’s POLICY — typical terms: credited on 4+ hours (half) / 8 hours (full), use within 30-90 days, manager approval, lapse without pay (the contested clause).
The Legal Backdrop vs the Policy Layer
| Factories Act workers | Working the weekly holiday → a substitute holiday within the month or next 2 months is statutory (Sec 53); hours beyond 9/day or 48/week ALSO owe 2x OT — comp off doesn’t replace the OT premium |
| Shops & establishments staff | State acts mirror the substitute-rest-day right with their own windows |
| IT/managerial/exempt | No statutory comp off — the HR policy is the whole entitlement; read its credit thresholds, expiry, and encashment clauses |
The Clauses That Decide Real Money
- Credit threshold: half-day at 4-5 hours, full at 8 — logging 3 hours on a Sunday often credits nothing; know the line before saying yes.
- Expiry: 30/60/90-day windows; for STATUTORY substitute days, expiry without the day (or pay) violates the Act — lapse clauses can’t defeat statute for covered workers.
- Encashment: better policies convert lapsed comp offs to a day’s pay; silent policies create the dispute.
- Exit: unused comp offs in the full-and-final — claim them; many F&Fs quietly drop the line.
Worked Example
4 holiday days worked + 1 banked, 60-day window, ₹3,000/day: 5 days = ₹15,000 of leave value on a use-it-or-lose-it timer — calendar the expiry dates; at minimum negotiate encashment-on-lapse in writing for repeat weekend work.
Practical Positioning
Email trails ("working Sunday per X’s request — logging comp off") create the record informal arrangements lack; comp off + sandwich-leave policies interact badly (a comp off adjoining a weekend can trigger sandwich counting — check); and Factories Act OT money (2x rules) rides ON TOP of substitute days for covered workers.
Frequently Asked Questions
Is comp off a legal right?
For Factories Act and shops-act covered workers, a substitute rest day for a worked weekly off is statutory; for exempt/IT staff it exists only as company policy.
Can comp offs expire?
Policy comp offs: per the written window (30-90 days typical). Statutory substitute days: expiry without granting the day (or paying) breaches the Act for covered workers.
Does comp off replace overtime pay?
No for covered workers — hours beyond 9/day or 48/week owe 2x OT regardless; the substitute day covers the REST-day right, not the premium.
Are unused comp offs paid at exit?
Where policy provides encashment, yes — and claim them in the full-and-final either way; silent policies are negotiable disputes.
How do I protect my comp offs?
Written logging at credit time, calendar the expiry, and get lapse-encashment terms in writing when weekend work is routine.
