Through my previous employer's complete incompetence and lack of a spine I had to work two days during my last holiday. He'd managed to approve time off for all three of the remaining staff at the same time, so as a compromise, our six day work week was covered by all of us for two days a piece. Sooo maybe not technically not coding on holiday?

The business could just about scrape by on one staff member, so the boss should've allowed the holidays to those who requested it first (myself and one other), but that would've caused problems with the third person who he just so happened to be related to.

I was made redundant a few months later. The company is in the a lot of trouble and on its last legs, but the one member of staff who kept their job was the least capable and, surprise surprise, the relative.
