Right. A lot of times they will have residents technically in the category of "unpaid employee," and your paycheck isn't really a "paycheck," but instead an educational "stipend." Not a big deal, right?
Think again. This can allow them to manipulate who gets what benefits. Where I trained, we were under this status and not eligible for a few of the "employee" benefits such as this, because we weren't "paid employees." We were "unpaid" employees and basically volunteers/students with an educational "stipend," according to the hospital.
This status allowed us to be ineligible for many of those employee perks, because we weren't paid employees. Yet somehow being unpaid "students" with an educational "stipend" didn't get us out of having to pay taxes on our paycheck which we were told wasn't "pay," but was an educational stipend.
Hmmm....
It's manipulation of terminology and employee status to make sure the hospital/institution gets the best of both worlds, financially. For them.
