I know of at least one industry where companies tend to stipulate that you must live within a certain distance and/or commuting time of your place of work. The idea is that fatigue during commuting adds to fatigue on the job and vice versa.
The investigation into the tram crash at Sandilands near Croydon found that the driver of the tram was severely affected by fatigue, his colleagues had reported similar problems, yet distrust between the workers and management meant that it had not been reported effectively.
So, it can cause very serious problems, I suppose one of the solutions is to live fairly close to work and/or avoid driving.
