The records
What has to be kept, for how long, and what it will support when somebody asks.
What Has to Be Kept
The record-keeping obligation is usually short, specific and wider than the payroll data, and most organisations are keeping the wrong half of it.
How Long
Retention is set in three places and they disagree: the regime, the policy, and whatever the system was configured to do when it was installed.
The Average as a Record
A figure nobody computed is still the figure. Computing it creates a record, and some organisations avoid computing it for exactly that reason.
Corrections and What They Must Show
Hours get amended every day for good reasons. What the record keeps about those amendments is what decides whether the whole set is evidence or assertion.
What Gets Asked For
Inspectors, representatives and lawyers ask for the same seven things in roughly the same order, and two of them cannot be produced after the fact.
What the Records Will Support
Working time records end up settling disputes about pay, discipline and liability, and they carry very different weight depending on provenance.
What a Working Arrangement Looks Like
A description to hold yours against. Nothing in it requires new systems, and most of it is a report that was specified and a page that was written.
