It's Ok because he's just accepted another job (which they don't know about).
he works in sales and was put on poor performance (written warning) for not meeting his monthly target. As a bit of background, his targets are ridiculous, nobody has ever met them, including his boss who has sold considerably less than him. Also one of the poor performance months was when he was on paternity leave, which they told him he was not allowed to take but he insisted.
Anyway, he was leaving anyway so he's not that bothered.
However, his boss has told him it would be better for him to resign than be sacked.
Can they just sack him? Would he be better of resigning or would they have to pay him off either way. Or would it be better for the company if he just handed his notice in?
Help!
