This "probation" thing is an insult to the hard working employees that have worked so hard over the years to help build this company. Create a new standard that puts performing everyday employees in a stressful bind so the company can pretend they have an excuse to fire you. "You have always been a good employee, but now that we have made up a new numbers game of evaluation we are probably going to fire you because we have decided to now call you an "under performer" This company is telling us to leave. Listen to them and save yourself some heartache. You can't win when they have rigged the game.
