Employees of Deluxe Entertainment’s postproduction facility in Culver City, Calif., have voted to unionize.

The results were announced following balloting Wednesday in an election conducted by the National Labor Relations Board over the question of whether to be represented by the Motion Picture Editors Guild and International Alliance of Theatrical Stage Employees (IATSE).

The bargaining unit consists of about 30 post-production artists and technicians. The facility is on the Sony Pictures studio lot at Stage 6, the former site of Sony’s Colorworks post-production facility.

The union said that many of the Deluxe employees are former Colorworks staff who took a cut in pay and benefits when Sony transferred control of the formerly unionized facility to Deluxe earlier this year. IATSE said Deluxe management has campaigned to discourage employees from unionizing by requiring employees to attend mandatory anti-union meetings and distributing anti-union campaign materials through company email.

“Post-production professionals recognize the value of having a voice at work,” said Rob Callahan, National Organizer for the Motion Picture Editors Guild (IATSE Local 700), “and today they spoke resoundingly. Deluxe prides itself on offering world-class post-production talent to its clients, and we look forward to sitting down with the company to negotiate a world-class contract for those employees.”

Deluxe Entertainment is owned by Ron Perelman’s MacAndrews and Forbes. The Motion Picture Editors Guild operates as IATSE Local 700.
