There's two stories out there right now about that.

The prominent one, including from local sources, appears to be that he was an electrician for 20 years, 17 of them at Molson Coors.

Milwaukee Journal Sentinel
"Anthony N. Ferrill, 51, had worked as an electrician for more than 20 years, about 17 of them at Molson Coors, according to multiple sources and online employment records."

From Heavy:

Anthony Ferrill, identified as the gunman, worked at the MillerCoors brewery, and later at the Molson Coors brewery, for more than 20 years, as an electrician.

From a 2019 article

MillerCoors announced a major plan to reorganize its business model on Wednesday.

The MillerCoors name will officially be retired and the company will be called Molson Coors Brewing Company.

So it sounds to me he has worked at the same place, and that restructuring plan entailed a name change to the brewery.

Still confused, but that's normal. 8>)
