Ft to temp Pt question

So for context, I transferred back to my first store. I have been full time since getting hired in 2022.

The thing is, transferring back I had to take a Pt position temporarily (1-3 months) due to someone possibly leaving in that time frame. After they leave, I’ll get full time again.

The thing is, I’m very reliant on the insurance, I’m a diabetic. My questions are: does the insurance cut off the moment I took the Pt? Or will it carry for a while?

I’m really nervous about this and I get a lot of anxiety calling HR due to past issues with them. Nothing bad but like, they do not care at all.

Does anyone know this information? Am I screwed till next year?

I’m young enough to be on my parents insurance but I lose that at the end of December.
