Sen. Heather Sanborn, a Democrat, owns Rising Tide Brewing with her husband. The National Labor Relations Board’s website says the business received a signed charge on Sept. 16.

The labor board states that the complaint charges Rising Tide with violating a rule against discharging employees because they urged other employees to join a union. The complaint does not list the name of the employee.

Sanborn said Rising Tide left the decision of whether to unionize up to employees in January and they decided not to. She said she’s “confident that when the National Labor Relations Board examines the facts, they will find that we conducted ourselves entirely appropriately.”
