Gemini,  I hear ya and do sympathise.  However I have learnt over the years that you are in fact just another employee and sometimes you are not given privileged information for fear of others hearing about it.  We all know PA's are privvy to some inside information from time to time but just imagine if you were another employee on the shop floor or in the canteen ... would you really be required to know what was happening before anyone else?  Probably not, which is why we sometimes expect more as PA's.  On this occasion I'd let it go...the decision was made which the company thought was for the best.  At the end of the day you are there to perform a job unless told otherwise.
