This is not a need that all of of us have. Nor is a commute an effective way for all of us to disconnect from work. It very much depends on both the person and workplace in question. Where it apparently is a serious need for you, I'd second some of the other suggestions on finding your own replacement, maybe something along the lines of set an alarm for end of day, turn everything off, and get out of the house and walk/bike.
