We are having a stock-take at work over this weekend, a memo was issued with the line "all managers are expected to be available"... so I'll be working on Sunday.

The thing that's going to make it extra painful is that the shift starts at 7.45am and I need to allow at least 2hrs to drive up there, my boss lives down this way too so we are going to drive up together, departing at 5.30am!
