"stress is factored into his remuneration package"
What a ludicrous thing to say.
People who shoulder a lot of responsibility do expect a certain amount of stress to come with the territory, and they have to handle it as best they can; that applies to ambulance crews, firefighters,doctors, and Chief Executives of major banks. The stress levels can vary however, and sometimes people crumple under the strain. It isn't their fault, and they have my sympathy. I've seen it happen,and it's not pleasant.
Saying that stress of that kind is 'factored' into a remuneration package is ridiculous.
