I have a neighbor who has been working at a beauty mega-store for about 6 months. His boss claims to love him. But he only works around 12 hours a month. He gets one 4 hour shift a week and at least once a month gets called and told they don't need him that day. The store is honestly crawling with associates. Most of them have other jobs, of course.
What is the advantage to the business to hire so many more employees than they need?
