PIP is only an excuse and documentation proof for your future dismissal. So that they have bullets to shoot you with you unable to countersue or lodge complaint for unfair dismissal.

Sure some people do complete their PIP supposedly unscathed and continue working but those are more exception than norm. Chances are they already have the target board on their backs and is placed in fridge for any consideration for BIP.

If you really intended to climb up further in your career, then it's time to make a jump if you kena PIP. Even if you like the company/culture/environment or whatever benefits, you jump out first. Go a few other companies and build your value then you can go back to that company with a different role or position. But chances are once you're out, you won't want to go back there because the grass is always greener on the other side.
