"Kind? Why? I'd have fired his useless ass."
In a big company, you may not have the authority to fire people. And those who have it, not always have to suffer the issue those people bring, as long as someone shields them to keep the boat afloat.
Also, in some countries, firing people is not so easy as in the US - especially where unions blindly protect even the most useless ass - usually because they are from the same category. And who cares if those damages all the people who work hard and conscientiously, and are paid the same.
Anyway, I can understand someone may have temporary issues and an hard time working properly - so I can try to be kind and wait for the issues to be resolved. But when I find it's just a lifestyle, well, I'm not someone who can accept it.
