@alpineskier I am not being trying to be over complicated in my use of language, there is a process that any business has to go through to sack anyone, as an employer you cant just rock up for work someday in a bad mood and sack someone.
You have to "manage people out", basically to protect your company as much as possible from the wrath, expense and damage of the employment tribunals.
Companies have to put employees on a plan to help them get back to work, and set targets and goals. It takes a great deal of restraint as a manager to go though this process, and you have to be meticulous in following the rules to avoid the tribunal.
In my opinion it would be extremely difficult to performance manage someone with so much hatred for the company that pays their wages.
I could never work for a company where I didnt feel valued and genuinely enjoy what I was doing, so how people can sleep at night taking a salary while trying to destroy the thing that pays them that salary is simply beyond me.
