<human>: Can you give me a shortened version of the text?

Hi r/legaladvice this is a throwaway account.  I was arrested over the weekend on Domestic Violence and Assault charges (both Misdemeanors).  I was calm, cooperative, and asked for an attorney as soon as I was read my Miranda rights by the police.  I also did not share any information with the police besides saying we had a fight when asked what happened.  (Like all i said was "we had a fight" when i was in the back of the squad car).  I spent the weekend in jail and was bonded out on Monday.  

My former partner met with my coworkers while i was at jail and told them her version of events.  [Major piece of information: I have a collective bargaining agreement at my workplace].  Anyway, my employer suspended me with pay following the allegations and launched an investigation.  As part of that investigation there was an investigatory meeting where my employer brought up specific allegations (which I have never mentioned and are no where but on the initial documents that I received from the police), questioned me if i had a protective order against me (i hadn't been served at that time and still have not been, though i am sure it is a natural part of dv charges), and implied that by me not answering their questions I was inherently guilty.  None of the information that they brought up was publicly available and now (outside of the tons of personal issues related to actual criminal case).  My answer to all of the questions that my employer brought up was "my attorney has advised me not to answer any questions about the ongoing criminal investigation that i am involved in". 

Is my employer allowed to operate on the premise that I am guilty until proven innocent?  Do any of their actions seem legally questionable? Should I start recording future meetings with their consent?  Any other tips or advice?
