Posting an open shift and letting staff claim it

An unfilled shift can be offered to everyone eligible for it. It appears on their phones and the first person to take it gets it.

Two nurses tapping claim in the same second is a real event, and it is handled where it has to be — inside the database, under a lock. Exactly one of them gets the shift and the other is told it has gone.

The offer only reaches people who could legally work it: the right role, no clash with a shift they already have, enough rest since their last one, not on approved time off, not over their hours, and no lapsed or missing credential the shift requires.

If somebody expected an offer and did not get one, their record usually says why.
