Read every gate punch against the shift
A plant with three shifts has three different on-time moments. A punch at 1:55 pm is on time for a B shift worker and an early exit for an A shift worker who should leave at 2 pm. So the rules must know each worker's roster before they judge a punch. Set a short grace at shift start, for example 7 minutes, and decide whether it also covers the walk from the gate to the machine shop, which can take several minutes in a large plant.
- A shift 6 am to 2 pm, B shift 2 pm to 10 pm, C shift 10 pm to 6 am
- General shift 9 am to 5:30 pm for stores, planning and office
- C shift punches that end the next morning filed to the day the shift began
- Double finger presses at the gate within 60 seconds counted once
Late marks, half days and missed punches
Shop floor rules must be simple enough for a supervisor to explain at the gate in Hindi, Marathi or Tamil. One workable rule: 3 free late marks a month, then half a day deducted for every further 3; arrival more than 2 hours after shift start counts as a half day; a missing punch-out counts as a half day until corrected.
Missed punches are common when a worker leaves through the scrap yard gate or skips the machine during the rush at shift change. The worker raises a correction with the real time, the supervisor confirms, HR approves, and the original punch stays on record for any later wage query.
Worked example: one press operator, one month
Ramesh Patil is a press operator on the rotating shift at a Chakan auto components plant. In a month with 26 scheduled working days he is present on 24, takes 1 day of approved casual leave and is absent without leave on 1. He has 4 late marks. With 3 free late marks and half a day deducted for every further 3, his fourth late mark costs nothing yet. One missed C shift punch-out is corrected by his supervisor. Result: 25 paid days, 1 day of loss of pay, and no late deduction.
Closing the month in the time office
Close the month in a fixed order. Clear pending corrections by the 2nd, scan the absence grid by department for days that look wrong, check that C shift days sit on the right date, then finalize. Finalizing freezes attendance, so payroll reads the same paid days the supervisors signed off. If a correction surfaces after close, reopen the month with a reason instead of changing pay by hand. The reason stays on record, which helps when a wage dispute reaches HR months later.
How to set it up in ZeniaHR
- Connect the gate biometric devices so they push punches over ADMS (iclock), or use Excel import or eTimeOffice sync if your time office already runs on it.
- In Shifts & Roster, edit the default shifts to your A, B, C and general timings, with grace minutes and the night shift flag on the C shift.
- Assign each department's rotation in bulk for the coming month so every punch is judged against the right shift.
- In the attendance rules under Settings and Policies, set free late marks, the every-N deduction and the missing punch-out treatment, then run the dry run on last month before switching on.
- Set correction limits per month and days back so missed punches are raised within the week, not in the last two days of the month.
- Finalize the month in Attendance Punches once corrections are cleared, so Direct Payroll reads frozen paid days.

How do factories record attendance for three shifts?
Most factories use a biometric machine at the main gate and match each punch to the worker's rostered shift. The A, B and C shifts each have their own start time and grace period, and the C shift that ends the next morning is counted to the day it began. The time office reviews exceptions every morning instead of reading the whole muster at month end.
What happens if a factory worker forgets to punch out?
The day shows a missing punch-out and is treated as your attendance rules say: half day, absent, or paid up to shift end until corrected. The worker raises a correction with the actual time, the supervisor confirms it and HR approves. ZeniaHR sends a missed punch-out alert 60 minutes after shift end, so the worker hears about it the same day.
How should late marks work on the shop floor?
Keep one short rule and apply it to each shift's own start time. For example, allow 3 free late marks a month, then deduct half a day for every further 3, and treat arrival more than 2 hours late as a half day. Show the rule to workers in plain words and cap the monthly penalty so one bad week does not wipe out a wage.
