What is a lone worker check-in?
A lone worker check-in is the arrangement by which a cleaner working alone confirms they have arrived and left safely, with a defined response if they do not.

</figure>The escalation is the part that matters. A check-in system nobody monitors records that somebody did not check in and tells no one, which is worse than no system because it creates false assurance.
It has to work in the conditions the work actually happens in — early mornings, empty buildings, poor mobile signal, and sites where the cleaner is the only person present.
Knowing who is on which site at any moment is also what makes an emergency response fast, and that is a records problem rather than a safety-equipment one.
In practice
A check-in system that nobody monitors after midnight.
Cleaners text when they arrive and when they leave. The supervisor reads the messages in the morning.
That is an attendance record rather than a lone worker control. The value is entirely in somebody noticing a message that does not arrive, at the time it does not arrive.
A system with no watcher is a log.
What goes wrong in practice
- Missed check-ins noticed at the end of a shift rather than at the time.
- Escalation contacts out of date or not available at the hours the work happens.
- Sites with poor signal treated the same as everywhere else.
