With my mob its 2 attempts then forget about it. Best start looking around as career F/Os are officially first inline for the chop in a down turn.
Some times moving on is the best thing as a different operation provides a fresh start and another go a few years further down the track could result in a first time pass.
I know someone who was told he'd never be Captain in the airforce on transports, same thing in his first airline yet managed the upgrade in Cathay Pacific and rose to a senior position.
