I honestly think your employers have been super generous already, one ought to know what is expected of him/her and realise they shouldn't leave themselves open to criticism by abusing the trust of the employer, always be in a positive balance, put in more than you take out and make sure it gets visibility.

I wouldn't keep someone who is not performing for whatever reason, because by the time I lose trust in that person, in my mind he's pretty much out of the door. Because this is business , it's not a charity , one is responsible for their own life.

As for those who say ' company culture and fairness ' I say your competitors are already eating your lunch
