I can't believe mgmt(or maybe I should have expected it!), sent out this memo. As a FA, Please tell me when was the last time a flight was delayed because of FA's?...it's just another way of HORRIBLE MGMT. NOT KNOWING WHAT TO DO!...AND NOT FIX THE REAL PROBLEMS....like congestion at gates, cramped and tight seats on a/c, carry-ons, bad computer system, that still has problems with dupe seats, wrong pax at exit rows, families not sitting together(and gate agts. passing the problem to FA's), no pause with preflights, and the list goes on....BUT don't take care of the real problems, just pass it on to the FA's. I for one, am tired of this incompetant MGMT. team that won't fix the interior of our planes, broken videos, BAD catering, bad customer service, and than send a memo to FA's about on-time. I will refuse to close that door one minute early, until everything that should be done on the a/c is finished for boarding. If the departure is 1400, the door closes at 1400(unless all procedures are done before that). I will not be intimitated(spelling) by the gate agents, nor MGMT. Where is the union about this memo?
