It's even better if your job requires you to average X amount of hours over Y period of time, or else you lose health coverage. Like at my last job.

Meaning if you get sick, and work doesn't provide enough "sick days" for your absences to be "covered," every time you call out, the hours you miss get tallied into a monthly average. If that average gets and stays too low, your coverage gets dropped. So you're stuck in a trap where in order to use your healthcare, you have to remain healthy. Deal with a chronic illness? Work a job where you're frequently exposed to ~~children~~ germs? There's another pandemic going around? Dare to be sick three days in a row? Good luck both looking out for your health and keeping your health insurance.
