[MN] returning from leave - worried about being let go
Good afternoon. A little over a month ago a recommendation was made by one of my healthcare providers to take a break from work due to declining mental health, as well as not having a good grip on my anxiety. My employer (very large multi-national media company) is very generous to offer STD at no cost, which I decided to take advantage of while out alongside Minnesota's new Paid Leave program, and I am not FMLA protection eligible having been with the company for just shy of a year. Prior to this leave, I was placed on a PIP. Our company is methodical in how they operate with these as it either progresses to a higher stage or regresses to lower depending on performance for that month. Only two weeks in the month had passed prior to my leave and I had sales come in during those first couple of weeks, however I'm unsure at this point if my goal would be prorated for the time that I was working in the month - I will find out when I return later this week. Not looking for advice on that piece.
My understanding with leave is that we are only protected THROUGH it, not necessarily after - especially with MN being one of many at-will employment states. I have some concerns around being let go when I return from leave later this week. Does anyone know if there are any other protections either related or unrelated to these types of leave (obviously not counting FMLA since it's not applicable) upon return? Things have improved drastically with medicinal intervention and an overhaul with how I go about my days, but I'm well aware that an employer doesn't owe me anything, including benefit of the doubt.
Happy to provide any clarifying information if requested/needed. TIA!
