It's a bit late now but I think what might have saved jobs was IF in the past Revisions had been "Truthfull & Realistic"
A lot of the workforce were compicite in helping to produce a distorted vision of the ammount of work required in their DO.
A lot of these habits developed over years as a tactic to deal with the constant daily arguments that Posties were having with lazy, incompetent Managers who were also passing on a distorted view of their DO's to their Bosses .... "Yeah everything's great Boss ... No problems the decks are cleared..... Can I have my Bonus now"?
It's no wonder that Management further up the line have NO IDEA what's happening in their DOs, because they've never encouraged Truth & Transparency from their Low Level Managers .... because they were only interested in their Bonuses!
Years later it's now hard for us to turn around and say "Well Yes it "should" have been taking me longer than I said to complete this duty ... but I just wanted to get finished and knock off ..... IF I'd delivered it as you wanted me to it would have taken too long"!
