A service bay does not run on a clock. It runs on job cards, spares availability and the fitter's torque wrench. A hatchback with a clunking suspension will sit on the two-post lift until the technician finds the perished control-arm bush, whoever's shift ended. That is why attendance and leave rules in a vehicle service centre must bend around the workload and still stay predictable. This guide gives a rule set for garages, motorcycle workshops, tyre bays, body shops and inspection lanes.
Start from the lift, not from the register
Start from the shape of the day. Early morning brings walk-ins, pre-booked periodic services and PDI checks on new stock. Mid-morning is the OBD scanner and road-test peak. After lunch the pending spares reach the stores counter. Evening is the delivery crunch, with owners waiting at the cashier for the invoice and gate pass. Saturday and Sunday run hotter than weekdays. Write down how many bays, scissor lifts, alignment rigs and pits you run, and how many technicians, torque-wrench hands and helpers each needs at each hour.
- Service advisors cover the front desk from the opening hour to the last delivery.
- Technicians and mechanic helpers cluster around the OBD-scan morning and the post-lunch spares window; the tool crib keeper and the stores clerk fill the gap.
- Washers, vacuum hands and buffing polishers are needed just before handover, not at opening.
- Body shop painters and denters work to paint-booth cycles, not to the clock.
- Inspection lane staff follow the booked slots, brake roller tester and headlamp aligner included.
Six rules that survive a Saturday
- 1
Post a base shift and a named relief
Each spanner hand has a start time, a rest day and a named relief for the pit or lift. A Sunday workshop with no relief list lives on frantic phone calls to the mechanic's village.
- 2
Define a late mark in black and white
Give the grace minutes, who writes the late mark in the muster, and when three marks cost a half day. The foreman and the senior mechanic follow it too.
- 3
Rotate the weekly off
Stagger offs so only a set number of technicians are away on a Saturday. Pin next month's chart on the notice board before the month turns.
- 4
Put the extra-hours rule on paper
Name who may approve extra hours, how far a job card may run past closing, and whether pay or a compensatory off follows. Note the card number beside the signature.
- 5
Fix a leave route
Planned leave goes to the workshop manager days ahead, before the monthly spares order. For a family emergency, a call before opening and a line in the register afterwards will do.
- 6
Review on Mondays
Sit with the foreman and the service manager, go through late marks, extra hours and unfilled lifts, and settle any pattern before it hardens.
Battery work in EV bays cannot be swapped around
An EV service centre cannot slide just anyone into a high-voltage task. Only trained, authorised hands isolate the pack with the service plug, wear insulated gloves and test insulation resistance on the HV cables. If that person is on leave, the job waits. Plan those roles with longer notice, a second authorised technician and a rule against starting a pack removal near closing time.
Tyre bays, detailing studios and bike workshops
Tyre service centres run on fitting speed. The bead breaker, tyre changer, wheel balancer and nitrogen inflator do not wait, and a puncture queue in the monsoon can double the load by noon. Detailing studios run on curing time for ceramic coating, paint correction passes with the rotary polisher, and the weather for outdoor drying. In both, the rota must allow a long job to finish without leaving the customer waiting or forcing the technician into a double shift.
See how the same issue plays out in tyre service centres and vehicle inspection centres. The attendance, shift and leave process page explains how we design the rule set.
The paint booth sets the pace in body shops
A body shop moves in stages: dent pulling with the slide hammer, putty and sanding, primer, spray booth, baking, polishing. Each stage hands over to the next, and a gap at the booth stops the line. Painters and the booth operator need tighter attendance rules than the denting crew, because a missed baking slot costs the whole car a day. Treat the booth schedule as the anchor, and build the roster back from it. Keep a spare helper trained on masking tape, sanding blocks and mixing the paint shade code, so the line does not stall when someone is absent. Ask the insurance coordinator to share the estimate approval dates early, since surveyor delays create sudden overtime when approvals land together.
Motorcycle workshops add another pattern. Riders arrive in a wave before the weekend ride, and engine-oil changes, chain-and-sprocket lube, carburettor cleaning and brake shoe jobs pile up between 5 and 8 in the evening. Rostering a late wave of mechanics, with an earlier start for the rest, shortens the queue at the washing ramp without stretching anyone.
What goes in the workshop file
- The muster sheet, initialled by the foreman at opening and at the evening round.
- A pit-and-lift chart with the relief list pinned beside the tool crib.
- Extra-hour slips cross-referenced to the job card and the registration number.
- A leave book with dates, balance and the approving manager.
- A monthly late-mark tally for the foreman and the HR lead.
