Schedules are awful. They will make you work 4 hours a day for 5 days a week. They dont even look at the schedules before giving you them sometimes and will have you on schedule all 7 days of the sunday through saturday week. Schedules will go against your availability.
There will normally only be one person scheduled on a sunday for the busy hours. managers will not care or help. If you need your breaks u need to plan them way ahead of time and hope that you can manage to take them. Then they also try and give too many tasks and spread you thin and complain when you cant do half of them because you dont have enough time, and the time they think you do have you have to manage watching kids.
