A friends son got a job collecting trash this summer at the city

Sea Isle City - A friends son got a job collecting trash this summer at the city works. He was told that if he did not work six days a week and stay after work to work in the trash drop off center, he would be terminated. She did say it was in a meeting with all employees not just singling our her son. What kind of tyrannical boss does that. They all work very hard and to be forced to work extra hours or be fired does not seem ethical let alone legal.
