Dairy associates

These questions are for dairy associates in specific. I work alone in the dairy. I arrive at 2pm as the first and only dairy person for the day.

Is it reasonable to think I can have milk and eggs 100% filled at the end of my shift if I'm alone? We're only allowed to do compost and trash once a night and that's at 930pm. By time we're done with those and I've taken my second break I'm expected to make sure milk is 100% full and so are eggs as well as all no empty crates and milk pallets. I'm also supposed to clean the 4 or 5 disposal buckets, egg cart, and of course sweep and mop the cooler.

Is it even reasonable to just have one person working in the dairy cooler?
