What really counts are the results you achieve in the long run rather than the initial impact you have. No matter where you work, office politics will have to be addressed. Be observant and learn how the different managers are perceived and the current political issues. Pick your new business friends carefully. Who you associate with can have a significant impact on how you are perceived.
Every company has some employees who thrive on spreading gossip.
That person who latches onto new employees quickly and acts like your best friend is very likely to be a gossip. Take time to know a variety of people and understand the culture before you start developing opinions and business relationships. Initiate communication with peers as well as people above and below you in the hierarchy. Present a positive attitude to start new relationships on the right foot. This is your time to adjust to the culture.
