As a result, HR can often make it extremely difficult, if not impossible, to hire backfills or additional staff and hence managers quickly learn that it is better to retain a 60% effective person than have no-one at all.
This lesson is even further reinforced when managers are forced to sack staff to hit some corporate cost take-out target which means they have to cut staff regardless of the teams actual resource needs and without the 'low performers' in the team, you would have to cut the good performers.
It's a sad state of affairs, but one I've seen on so many occasions.
I bet they would, but such a system would be wide open to abuse. So the market has fixed it: contractors. You can get rid of them easily when no longer needed, but you pay a premium while they are.
Good stuff. I think leaders in general need to be more proactive pruning their employee tree if they want it to bear good fruit.
I'm amazed how difficult it is for managers to admit that they made a hiring mistake, even if the person that needs to go is just a contractor.
