How to navigate through office politics?

This is all very context specific and depending greatly on the office environment you’re in and what your goals are in the environment. Without knowing any of that information, one can only provide the most basic advice.

The best approach to avoid office politics is to not involve your self with it. Just be a good worker, come in on time, leave on time. Just work 40hrs and do just the job outlined in your job description. Do not involve your self in initiatives, unpaid work, or declare a preference for assignments. Do not expect a promotion or dramatic pay raises. Live your best life outside of work and find a new employer when your current one no longer suits you.

Leave for somewhere with better managers, so you don’t have to put up with office politics.
