Hi,
I'm a bit lost, the 27th is that a bank holiday? it isn't listed as one on the .gov site.
I'd noted I'm set as having the day off as annual leave but unsure if it is actually being forced, when I started my current role I wasn't told about any particular Christmas shut down in operation, for the period inbetween Christmas and new year and xmas eve, I recall we specifically had to book leave if wanting to be off as I understood it and I hadn't applied for this day off as leave.
