Season 2 Edit
In the episode "The Carpet", Michael Scott asks Ed for advice when he feels the employees don't see him as a friend. Ed explains to Michael that as the boss, he will never be his employees' friend, a claim that Michael refuses to accept. Ed's advice is to let "your workers be your workers, your family be your family, your friends be your friends."
Before their conversation, it is suggested that Michael has lured Ed to the office by telling him that there has been a problem with his pension. When Ed enquires about it, however, Michael simply says it was a clerical error that was cleared up before his arrival.
Michael claims that Ed Truck (his old boss) was the opposite of fun and that when he walked by people pretended that they were working. Michael never wanted to end up like Ed Truck and be the boring boss.
Season 3 Edit
In the episode "Grief Counseling," it is revealed that Ed Truck had died. Creed Bratton claims that Ed was decapitated in a motor accident, but this may be untrue, given Creed's history of outlandish and inaccurate storytelling (such as a story about Dwight being decapitated). According to Michael, Ed was almost 70 years old. Michael doesn't take his death well (only after he gets a consolatory hug from Pam), leading to Michael's desire to stage grief counseling sessions with his employees.
Season 4 Edit
In "Dunder Mifflin Infinity," Jan Levinson mentions that the company tried to force out older managers by instituting a mandatory retirement age. They were forced to back off because Ed Truck filed an age discrimination lawsuit.
