While every job--hell, any place you need to interact with other people--requires us to tamp down certain aspects of ourselves to get by, a new study suggests that doing so too much can take a toll on your health in the long term, and also just doesn't feel that great, according to New York Magazine. The researcher took 300 employees at a UK marketing firm and asked them to complete a personality test, as well as fill in a survey about their work lives. This was compared to HR data (provided with the employees' consent) on performance reviews and promotions over the years. What was found was that people with naturally talkative and outgoing personalities had less job satisfaction and more stress when required to be quiet and solitary for long periods of time, and that similarly more quiet and introspective people felt less satisfied if they needed to interact with people for a long time (though the study did note that extroverted people tended to suffer more from having to act out of character). New York Magazine noted that other research suggests that having to forcefully suppress parts of your personality for extended periods of time, such as work, can also lower immune functioning. The takeaway from all this could be that it's important to find a job that fits your particular personality and best serves your strengths.
