You are correct actually, in one of his 2016 vlogs TDW 1544, Adam shows all the previous places he worked at in St. Cloud, and it was 5 years at OfficeMax.
Ok, so if what I'm understanding is correct, he used to legit work at OfficeMax (I DO remember that vaguely now), but he said in his recent vlog he worked at Staples?
I never 100% understood the difference between OfficeMax, Office Depot, and Staples, but a quick Wikipedia search brought up that OfficeMax and Staples were rivals.

Excerpt -
It'd be like if I told you all I worked at McDonald's (which I did as my first job), and then a week later said I worked at Burger King as my first job.
How does one make this mistake?
Unless...
ETA: Staples DID attempt to acquire OfficeMax but it didn't work.
So, by him saying Staples now, it's not even like he's referring to what OfficeMax later merged with and became.
