Notice period

[BlasterBates]

No I wouldn't give notice, not a good enough reason.

Not all contracts are briliant, and you don't want to be throwing in the towel everytime it's not quite right, then you spend half your time in legal wrangles and "getting angry" everytime you get an e-mail.

6 months is a very short time just turn down the the renewal.

If the work is clearly outside the scope of what is your role talk to the client and explain it's a breach of contract. You can then negotiate to leave asap which maybe that day.

If however it's generally part of the role you do - ask others you know who do your role - then shut up, do the work and turn down the extension.

No it's not. Most of my Ltd Co contracts have both ways notice periods, ranging from zero to 28 days on the client's part; maybe 7, 14, 28 on my part.

Antman's point still applies. Don't play games. Man up and negotiate your way out!
