PORTLAND, Ore. (AP) — Three employees at the famous Voodoo Doughnut in Portland, Oregon, were reportedly fired this week after they walked out during the Pacific Northwest heat wave. The Oregonian/Oregon Live reports that on-duty staff walked out of the shop Sunday afternoon, and planned to return to work Tuesday. That’s according to a statement from Doughnut Workers United, which had unsuccessfully attempted to unionize staff at the location earlier this year. A Voodoo Doughnut spokesperson declined to discuss the firings but said the store was air-conditioned and measures were taken to address the heat, including providing employees extended or additional breaks, and shifting production to early morning and late evening hours.
