The Victoria and Metropolitan lines will be closed on Boxing Day for engineering work. Management seem to think this means they can book all the drivers off on annual leave for the day. Problem is: that means you lose an annual day from some other time in the year.
We have little enough control over when we have time off work. We don't need management telling us exactly when we are off. They should just shrug their shoulders and give us an extra rest day. It wouldn't hurt them to cut us a bit of slack sometimes.
