The Amazon comedy series “The Marvelous Mrs. Maisel,” which had a good night at Sunday’s Golden Globes, didn’t get to celebrate for long before the show was dealing with an unfair labor complaint.

“The Emmy-winning Amazon comedy series’ production company, Picrow Streaming, has been accused by IATSE Local 52 in New York of making ‘coercive statements’ and ‘changes in terms of conditions of employment’ in violation of federal labor law that prohibits discriminating against employees because of their union activities,” Deadline reports. “The allegations are currently under investigation by the National Labor Relations Board.”

Rachel Brosnahan, who plays the title role, won the Golden Globe for the second consecutive year on Sunday for Best Performance by an Actress in a Television Series, Musical or Comedy.

“The union’s charge, obtained from the NLRB through an FOIA request, claims that over the past six months, Picrow has violated the National Labor Relations Act ‘by its discriminatory treatment of union shop stewards and supporters’ who ‘made complaints to management regarding hours and other working conditions during the film production of “The Marvelous Mrs. Maisel,”‘” Deadline reports.

Amazon denied the allegations, with a spokesperson telling Deadline: “Amazon Studios fully supports the entire team behind ‘The Marvelous Mrs. Maisel.’ While we don’t comment on specific personnel matters, these allegations are demonstrably false. Amazon Studios does not tolerate any form of discrimination or retaliation.”
