Relenting on the comedy a little, politics can be a serious issue so my prescription is: move every 2 - 4 years, depending on seniority. Politics favours the new entrant to the company as your own particular brand of politics are unknown, so you will be courted by the various players, you have the benefit of expectations being lower than your second year, and you can evaluate just who is making moves in the organisation with no position of your own to defend or compromise. By end of year 2 at mid management level you should really be looking for your exit options for year 3. Take redundancy if offered - it will keep you ahead of the market. The best way to play politics is to never show your hand - be everyones friend but ask them what they can do for you in return for your support. And get to know the really important people - not the partners, the PAs, the secretaries, credit control, finance, HR etc, these are the ones in the know, and power in an organisation ultimately rest with them as they keep a lot of secrets and can make the difference between your next project being a great one from under the radar or that public sector talent bin that keeps doing the rounds.
