Many individuals when they get a job that pays them well decide to keep for their life. This create a sort of comfort zone where the worker feels like home also if he's working. Working several years for the same company or in the same place, would help the employer to develope specific skills that he can use at his working place. For example, people who works as a waiter or chef in a resturant after 10 years of work he will know exactly the kind of customers the resturant has and all the expenditure behind it. Moreover people who works for their entire life in place have more chances to get an important role inside the company, for example, they can become head of department or CEO instead of being a classic seller.
