There is still a pandemic. There are still far fewer passengers. There is still danger in coming to work.
Sorry for stating the obvious, but it appears that some managers have forgotten.
In order to reduce infection risk, early in the first lockdown, stations adopted 'pandemic rosters', in which staff work shorter hours and have more days off. This meant less exposure to the virus, less absence for sickness and self-isolation.
It's working well. But despite not being broken, management at St Paul's decided to fix it and put staff back onto the full roster. Risking staff's health would apparently be collateral damage.
The good news is that staff refused to accept this, raised it with their union, and once some noise had been made at higher levels, the roster is back to what it ought to be.
A lesson to us all.
