School caretaker, lives on site and is paid to work weekdays in the holidays.
During the holidays, there were building works going on and contractors were under pressure to get it finished, so they wanted to work weekends.
Caretaker refused to unlock, unless they paid him cash upfront, which they did, as they needed to get the job finished. Correct procedure would have been for him to unlock and claim overtime for his time, which would have been considerably less than the cash payment made (and he would have paid tax on it). That said, we're talking a few minutes, as he lives on site and the school may have balked at his OT claim. School would have passed any cost onto the contractors.
Now the school is open the builders have complained to the head.
I don't know what to say to him, other than why would you be so stupid, which is not helpful....
