Family unhappiness causes him to stay out of the home. With nowhere else to go, he stays in office for as long as he can and dives into work to keep his mind away from his marital problems.
Curing the habit for these lot of people will depend on the reason for them wanting to work long hours. A good boss should encourage his employees to have a balanced life. The best way to
do that is to be the exemplary figure. If bosses leave the office right after office hours, openly talk about their golf and other social hobbies, and party away on weekends, the workers are
likely to follow suit.
