About this site

Fifty notes on clock in / clock out systems, written for the people who have to defend the resulting numbers: payroll and HR staff, site and operations managers, shift supervisors, and anybody who has been asked why the hours paid do not match the hours the building saw.

What it covers

The boundary the clock marks and where it actually falls. The minutes before the punch — parking, walking, security queues, changing, machine start-up, briefings — and who requires each of them. The minutes after it. The periods inside the day whose status is unclear: breaks, standby, waiting, travel between tasks. The terminal as a piece of equipment, including where it sits and what happens when it fails. The translation from a punch into money. And what the records will support when somebody disputes them.

What it leaves out

Choosing and deploying a clock system, which is a procurement subject covered thoroughly elsewhere. Deliberate manipulation of the clock by workers, which is a disciplinary subject with its own literature. Both are legitimate and both treat the clock as the object; this collection treats the boundary as the object.

No product names, no vendor comparisons, and no benchmark figures. The durations used here are illustrative, and the only numbers worth acting on are the ones from your own gate.

Not advice

Nothing here is legal, payroll or accounting advice. What counts as working time, whether pre- and post-shift activity must be paid, what may be rounded or disregarded, and the treatment of standby and travel differ by jurisdiction, by sector and by collective agreement, and they change. Where a note touches on any of those it describes the shape of the problem, not the rule that applies to you.
