Look at almost any 24-hour rota and you will find shifts that abut perfectly. Earlies finish at 15:00, lates start at 15:00. Nights start when lates end.

Now ask how the incoming shift finds out what happened on the outgoing one.

The answer is a handover, it takes ten to twenty minutes, it happens every single day, and on that rota it belongs to neither shift.

Why this is more than a rounding error

Two things go wrong, and they go wrong in opposite directions.

Either the outgoing shift stays. Which means every person on every shift works ten to fifteen minutes beyond their finish time, every day, unrecorded. Across a care home running three shifts, that is somewhere north of an hour a day of unrecorded work, five to seven days a week. It is unpaid time if it is unpaid, it is uncounted working time either way, and it is the single most reliable thing to find when someone finally looks at clock-out data against scheduled ends.

Or the handover does not really happen. Which in a warehouse means the next shift rediscovers a problem, and in a care setting means clinically significant information does not move - a resident who did not eat, a change in behaviour, a family conversation that needs following up. In regulated care the handover is not administrative courtesy; it is part of how continuity of care is evidenced.

Most operations get a bit of both, unevenly, depending on who is on.

The scheduling error underneath it

The rota is expressing an assumption that is false: that a shift is a block of time during which someone does the job, and nothing else.

In reality a shift for most roles has three parts - the start-up, the work, and the wind-down - and only the middle one is what the rota describes. The wind-down is handover, cash-up, the equipment check, the log, the tidy. The start-up is the same in reverse.

The fix is not complicated. Overlap the shifts deliberately, and put the overlap in the rota.

  • Earlies 07:00–15:15, lates 14:45–23:00
  • Nights 22:45–07:15

Now the handover is inside two paid, scheduled, recorded shifts. It has a start and an end. It is visible in your labour cost, which is the point - you were already paying for it in one form or another, you just could not see it.

"That costs us thirty minutes a day"

It costs you thirty minutes a day that you are already spending. The question is whether you spend it deliberately or accidentally.

And there is a real return on making it deliberate. A handover with a scheduled slot tends to become a handover with a structure - a short list of what actually has to transfer - which is faster than the informal version it replaces. Several care providers who have formalised this find the scheduled overlap ends up shorter than the unscheduled overrun it replaced, because "we're on the clock for this" changes how it is done.

How to find out what yours costs today

You almost certainly have the data, if you have clock-in.

Take a month and, for each role, compare actual clock-out time against scheduled shift end. Then group it.

What you are looking for is not the average - it is the consistency. A role where nearly everyone clocks out eight to fifteen minutes late nearly every day is not a discipline problem and it is not overtime in any meaningful sense. It is unscheduled handover, and it has a shape you can read straight off the report.

Do the same at the start of the shift. In a lot of operations people clock in early and it is treated as their own affair, but if the start-up work genuinely has to happen before the shift can run, the same argument applies.

The sector versions

Health and social care - the highest stakes, because the content of the handover is clinical and because it is the thing an inspector will ask to see evidence of. Overlap here is usually 15–30 minutes and is increasingly treated as non-negotiable.

Logistics and warehousing - the handover is about what is half-done: a pick that was interrupted, a bay that is blocked, a machine playing up. It is short but it is the difference between the next shift starting and the next shift working out where things are.

Hotels - reception and night audit is the obvious one, and housekeeping has a quieter version: rooms that were refused, rooms with a maintenance issue, a guest request that spans the day. Departments hand over on different clocks, which is why a hotel is the easiest place for handover to fall down a gap between two rotas rather than within one.

The short version

If a task happens every day, takes a predictable amount of time, and has to happen for the operation to work, it belongs in the rota. Handover meets all three, and it is almost never there.
