We are happier when we "fit in" because we feel a sense of belonging. We also are more likely to develop meaningful friendships because we share values with others in a group. Fit affects our performance because our level of engagement and motivation are positively related to our level of fit.
Is fitting in necessary?
If you're planning on interviewing for a new job the most important thing that you can do is demonstrate that you can fit right in. And by fitting in, I mean that you're willing and able to seamlessly slide into the corporate culture.
Why is it important to fit in at workplace?
Fit employees are less likely to use sick days. When employees use less sick days, they contribute more to overall productivity. They also reduce the hassle of trying to find replacements at the last minute. Employees who exercise are much less likely to get sick than those who don't exercise.
