LANGHORNE, Pa. (CBS) — Local labor leaders rallied today with striking Neshaminy school teachers in a show of solidarity for the now one-week-old walkout in Bucks County.

Several hundred strong, members of the Neshaminy Federation of Teachers walked across Woodbourne Road from Maple Point Middle School into Core Creek Park, where they heard from a number of leaders from other unions.

They stood as one, vowing not to let the school board break their resolve.

NFT president Louise Boyd said there was no validity to reports the teachers will go back to work on Tuesday.

“Our members will be on the picket line, as is their right under Act 88,” she told KYW Newsradio today.  “We intend to be on the picket line until Thursday, and we will be returning to work on Friday, January 20th.”

The 650-member union has offered round-the-clock negotiating to the school board, but Boyd says she’s received no response.  The board has canceled all talks until the teachers go back to work.

Seven thousand students are affected by the walkout.
