When I applied for my job, I asked for Monday to Thursday.
They have given me Monday to Wednesday- AND Friday.
They said they'd take me off the Friday as soon as was possible.
It's been 18 months and they haven't. It's also the late shift which means I do not get a Friday evening (well, past 20:00 when I finish).
I am hardworking usually and have no qualms about working over my usual time to get things done or help someone but on a Friday I set my alarm on my 'phone to go off at 20:00 and I log out immediately.
Small thing-makes me feel a little better.
