Dude, if you're not doing something wrong then don't take it. Stand your ground and don't let a power game affect you.

The only way you can be removed, provided you're in a typical contract job, is if you are doing something genuinely wrong.

If you're not, fuck them. Play them against more important superiors or against themselves for bullied dismissal where the law absolutely favours the employee and not the boss.

If you're not contracted and actually want to keep the job then fall in line and belt up because they can let you go for whatever the hell they want.

On the other hand bear in mind that unless you're in the favour of the man who signs the contracts when yours is up that they will simply choose not to renew it. At least, that's how local councils prefer to sack people anyway.
