18. Mr. Phillips and Mr. Matthews
Jack Collins played Mr. Phillips in three episodes--#33 "Call Me Irresponsible," #37 "Coming Out Party," and #47 "Double Parked." He was mentioned a bunch of times, and Peter dated his niece Pamela in #111 "Two Pete's in a Pod." The Bradys jeopardized Mike's job in all three episodes. In "Call Me Irresponsible," Greg got a part time job with the firm, and lost plans he was supposed to deliver. In "Coming Out Party," Carol screwed up when she told Mr. Phillips that she "would never want to go on his broken down barnacle barge," mistakenly thinking it was Mike playing a joke on her. And in "Double Parked" Mike had to draw plans for a building to go on the site of the kids beloved park. Since Carol and the kids led the opposition, Mr. Phillips got pissed off.
Jim Backus played Mr. Mathews in one episode - losing to Bobby in a game of pool in #114 "The Hustler."
By the way, there was never a mention of the name of the company where they worked.
