Night shift absolutely sucks, and I’m deliberately lax on enforcing many of the store policies because of it. Late for your shift? If your shit gets done, I don’t care. Don’t like wearing the uniform? I don’t either, just put your name tag on before the store opens. Forgot your lunch? Grab something from the cold case or whatever and pay for it when a checker wanders in later.

The only policies I enforce 100% are safety-related. I don’t want someone cracking their head open because they were using a pallet jack as a scooter.

My store has shift work, but does it in a sane way. The people whose schedules could change bid for schedules on a week by week basis, and they’re awarded by seniority. In theory, you could get stuck with a closing shift going into an opening shift, but in practice it never happens because all the opening shifts get snapped up by the senior employees every week.

No, it’s not.

What the philosoraptor is saying is that literally any computer program is machine learning, which is untrue.

An expert system is a system designed to simulate an expert. It’s something you would seek advice from in some way. They’re used in medical diagnoses and stock market trading, for example.
