The problem is that for most companies, employee health is very far down the list in importance.
I worked at a company where my colleagues included two young brothers. One of them had a serious illness and was in hospital. One day the other brother, at work, got notification that his brother in hospital might not have much time left. He asked management if he could take the afternoon off to go and see his brother. They said no, they needed him to work late. This guy was an overly conscientious employee and he didn't go to the hospital that day. His brother died during the night and he didn't get to say goodbye to him. Those are the priorities of many companies.
