In an ideal world, but sometimes the wrong people get hired. A sacking during the probation period is still a sacking.
Luckily I'm not in a firing position in my role, I'd hate it, but I have been involved with firing someone before. It was fucking horrible.
At the minute, I'm probably going to have to fire someone.
I'm fucking angry about this for several reasons - angry at the clown that employed the person (he said he felt sorry for them - wtf), angry at the person being thrown in to a place where they would clearly struggle, angry at not being privy to the appointment in the first place.
My boss and his boss have been discussing how to progress and they don't want to fire her, but want her to be someone elses problem - i.e moved sideways.
In all honesty, I think firing might be the best thing for the person involved. A sideways move would mean more of the same and they'd struggle in that job too.
bad crack all round tbh.
A friend of mine was fired from his job recently, was shite but now, he's happier and whilst it was unsavoury at the time, it has worked out to be right and he's better off out of the mess.
Therefore, with those two examples, it is sometimes right!
