The very first thing to imagine when figuring out who has been at Dunder Mifflin the longest is which team used to be employed first. Ahead of Michael Scott took at the function as regional supervisor, he used to be a paper salesman, additionally employed via Ed Truck. The other folks whom Ed had additionally employed throughout his time as regional supervisor are discussed quite a lot of instances all the way through the sequence — those come with Todd Packer (David Koechner), Stanley, and Phyllis. Even supposing there is not any respectable rent date for the latter two, it’s identified that Michael set to work at Dunder Mifflin in 1992.
We will pull a couple of extra clues from the sequence to get additional info according to what we have already got. In Season 3, Episode 12, “Touring Salesmen,” Michael calls Phyllis the “resident senior,” suggesting that she has both labored there longer than any person else — or that she is solely the oldest of the gang. Some superfans might take into account that proper after that remark, Phyllis informed Michael they’re the similar age. This by myself proves that Phyllis has been operating at Dunder Mifflin longer than Michael, who used to be additionally held again in first grade. Michael did not get started operating at Dunder Mifflin till he used to be about 27, in comparison to Phyllis, who began a lot previous. This concept is additional confirmed within the circumstances when Michael claims Phyllis has extra enjoy than him.
