So night people are often denied raises, passed over for promotions, or even fired. The perception is that they are that they are lazy, undisciplined, not punctual, or have an attitude problem. However, when members of the majority, day people, are forced to work night shifts, these same behaviors are observed and even expected. Why, they even call it the graveyard shift. Now some will claim that this is fair.
Business has to be done when other businesses are open.
If we make arrangements for you to work at night, then we'll have to force management to work nights. The majority of people prefer to work days. The traditional business day is the result of an unspoken collusion. There is absolutely no reason why most businesses could not be open at different hours. There would often be benefits to doing so.
