I have just been offered a very good job and want to leave as soon as I can. I am a senior with 15 years in and the time is right to go. I have to give 12 months notice, but I want to know if this has been challenged before by anybody and have they managed to get out any earlier. I am aware that I could get out in about 9 months but I want to go sooner. I think the 12 month thing must be illegal. Would appreciate any help.
