i'm not sure what to do (minnesota)

[trex]

Okay, I've posted here once before, so i'll quickly summarize and then hopefully someone on here knows what to do next....

i got a back injury in january catching a client from falling in the shower. the shower at the group home had been broken for a year, and they never bothered to fix it, despite our complaints. we also had no lifting equipment for this client (they got that shortly after i got hurt, and i was not the first hurt, just the worst hurt)

well, since then my employer has falsely disciplined me (i wasn't even at work to do anything wrong), threatened my job, suddenly the paperwork i had to file to have my other job was "unsigned" despite it being turned in 5 months ago, and they accused me of fraud as well as giving me an extremely low yearly raise compared to other workers(less than half of their raise) even though i had never been in trouble at work before.

now, they gave me a new job.... in a department they are closing in june. they waived the exact same lifting requirements that are listed along with my old position (which they refused to waive for me), yet my old position isn't closing. my fear is that they are doing this so they won't have to pay me wage benefits because "my position ended, not because i got hurt"

the insurance lady cut my benefits because she changed my wage determination, even though my employer is telling her i do have a set schedule, she refuses to go off of that.

i'd like to take my employer to court because i was injured and they knew the bathroom and lack of lifting equipment was a hazard, as well as their retaliation against me for filing workers comp. however, i keep hearing i need a workers comp lawyer, but then i hear that i need an employment lawyer and i have no idea what i need or if it's even worth pursuing.
