The OPs P-Cat won't change, but his MELs could. And his current MELs may not be on his pers file, as a new 2088 may not have been generated if the MELs aren't changing his category. There is nothing wrong with a supervisor asking for a member's chit that states his most recent MELs, especially if there has been a change from when his PCAT was issued. Maybe the OP has said "sorry, can't do that, I'm on a PCAT". Or maybe he has said "hey, I can do that now, x has gotten better since the PCAT, or I've adjusted to my meds so there are no worries". The supervisors are just doing their due diligence.
