I have been in my marketing job for two years and I have been getting disillusioned in recent months, mainly because the atmosphere has changed for the worse because of a change in personnel. I have considered looking for work elsewhere but now I have been offered a promotion.

It will be a more senior position and will probably be to the benefit of my CV and my career. I am a bit wary of the prospect of staying at the company though. What do you think I should do?
