Why do I stay here?

Conversation with Tall Colleague:

MrT: 'You know, TC, there are days when I really hate working here. Today is one of them.'
TC: [chuckles] 'What's going on here nowadays? Everyone seems to hate working here,' [in an 'I do too' tone of voice.]

In all fairness, I usually like my job but the past few weeks have been sheer hell in many different ways, and I have recently been put in a quite awkward situation. I'll soon be taking over a class from another teacher (under protest), who also happens to be a mate of mine, because the bosses have totally fucked him over and are making him take the fall for it after two colleagues stabbed him in the back.

Roll on, Christmas break!
