The battle between WHDH and AFTRA — the union that represents the NBC affiliate’s on-air talent — is heating up in Boston.

WHDH talent — including those pictured at left, Victoria Warren, Frances Rivera and Adam Williams (all wearing black)– protested outside the station’s annual Health and Wellness Expo over the weekend, waving signs that said, “AFTRA Contract Now!”

Much of the station’s talent has been working without a contract since last year as the union and the station attempt an agreement over salary and age discrimination concerns. The Boston Herald‘s Jessica Heslam reports that according to AFTRA, the Sunbeam Television-owned station has ceased negotiations in the fight.

In addition to the signs, WHDH anchors and reporters also handed out fliers outside the Expo, urging attendees to call station general manager Chris Wayland and “tell him you support a fair workplace for broadcasters.”
