For me, I am eligible for the same insuarance as full time if I work more than 32 hours a week.
All that means is that my dependents can be insured. I do not have any dependents so it doesn't make any difference to me.
I am in Michigan. If I average less than 20 hours a week, then my insurance can be paused for a quarter until I average more than 20 hours a week. Anyone on a later contract can have their insurance paused if they average less then 24 hours a week.
