Alright, well, you are much more likely to know what this is about than I am, so I can't even venture a guess without your help. However, I can discuss the law. The law, sadly, is that, at this point, your employer doesn't have to explain to you what is going on and also could, if they choose, terminate you for any, or no, reason and with no notice, as long as they don't violate a contract in doing so. The fact that they are paying you is good since there is no requirement that employers do that when they suspend someone. The only other exception to the termination
rule is that an employee cannot be targeted for termination simply because they are a member of a protected class under employment discrimination
So, at his point, you will have to wait for their final action to see where to go from there. As long as you are being paid you are still employed. Once payment ends, if they haven't contacted you to explain, you should contact them and ask for an explanation. If they don't give you one, then you can file or UI benefits and, at that point, they will have to tell the State why they terminated you. Again, at that point, you can respond as appropriate.
I can't tell you why they have your job listed, again you are in the best position to know that, but it appears that they don't plan on bringing you back to that particular job if at all.
Please feel free to ask follow up questions if you have them.
