Journalists at Johnston Press-owned Yorkshire Post Newspapers, who start a second four-day strike tomorrow, have given their management notice of more industrial action.
They will also leaflet the offices of the Press Association which has been supplying the newspapers with copy during the dispute, the NUJ said today.
The journalists will hold two further one-day strikes and four union meetings during works time over redundancies at the Yorkshire Evening Post, Yorkshire Post and Leeds Weekly News.
They will walk out again on Wednesday 4 March and Saturday 7 March if the dispute is npt resolved. They have given notice of holding mandatory chapel meetings on Thursday 5 March, Friday 6 March, Sunday 8 March 2009 and Tuesday 10 March.
NUJ members plan to leaflet Press Association offices during the strike after accusing the news agency of being "electronic strikebreakers" by supplying YPN with extra copy when the journalists are on strike.
The NUJ claims PA had dedicated reporters working for the Yorkshire Post and Yorkshire Evening Post and produced pages based on the papers’ usual templates.
Jenny Lennox, NUJ assistant organiser, said: “We were stunned by the sophistication of the Press Association strike-breaking operation. It has made us more determined than ever to recruit more PA journalists into the union."
