I've been doing my current job for a year and have not liked it for the majority of that. My line manager is very hard work (and fairly small business so can't change). There is a lot of pressure, most weeks I work 50+ hours and still he expects to pile more work on me.
I've got two other job offers but on lower pay (20% pay cut). At the moment I don't sleep well due to work stress, headaches, dread going to work. The only thing stopping me quitting is the slightly lower pay elsewhere, I'm a single parent so don't want to let my kids down (less holidays etc)
