Manager schedules 16-year-old homeschooled fast-food worker for 40 hours a week, calls her a lazy teenager: 'I cried at work 3 times today.'

She only asked to be scheduled part-time, but she's working full-time.

Any manager who expects teenage workers to have the same level of professionalism as adult workers is setting themselves up for disappointment. While some teens are incredibly committed to their after-school jobs, most are just doing it to get a little extra pocket change. An adult is going to take their job more seriously, both because of the stage of life they're at and because they are working to pay their bills and eat. Adults know that if they get fired, they might not be able to afford to eat. Most teenagers are supported by their parents, so they don't have the internal drive to work to survive. And even if they have a trace of that drive, they usually don't have the discipline and maturity to put it into practice. 

The funny thing about fast-food service jobs that pay pennies is that they expect all their employees to take the worst extremely seriously, even though virtually anyone can get one of these jobs, and they aren't paying their workers enough to be emotionally invested in the company's long-term success. My pet theory is that micromanaging service managers are just unsatisfied with their lives, and want to pick on someone smaller than them, so they harass teenage girls working their first job because they want to break their spirit. Any teenage girl who finds herself in a job where she gets yelled at for no reason should run far, far away and find a more chill job. The girl in this story, especially, should do that.
