Are National Labor Relations Board employees colluding with labor unions to rig union elections? That’s the claim in a 16-page complaint to the board filed by Starbucks on Monday that raises questions about the fairness of the Biden labor agency.

Few companies strive to be more progressive than Starbucks, but the coffee chain has become a leading target of union organizers. That’s typically a problem for Starbucks to address with better pay and benefits. But the company’s complaint, which is supported by evidence from an unidentified NLRB career employee, makes a strong case about union and NLRB misconduct in a mail-ballot election at a store this spring in Overland Park, Kansas.
