Starbucks asks labor board to halt mail-in union ballots - CNN

The NLRB workers in question "engaged in highly improper, systemic misconduct involving Starbucks and Workers United," the company's general counsel wrote in a letter to the NLRB.

Starbucks said an NLRB whistle-blower alerted the company to the alleged misconduct.

Some workers missed the deadline to vote by mail but weren't offered the option to vote in person, Starbucks alleged, encouraging a pro-union result.

The coffee chain also alleged that the NLRB workers gave the union information like when and how many ballots it received in the mail.

"In light of these types of misconduct by NLRB personnel, we request the Board immediately suspend all Starbucks mail-ballot elections nationwide ...

"The NLRB does not comment on open cases," said Kayla Blado, director and press secretary at the NLRB's office of congressional and public affairs, in a statement on the letter.
