Al Jazeera English journalists based in London have told management they will go on strike next month over pay.

Staff at the Qatar-owned broadcaster voted overwhelmingly to take industrial action in March following a years-long dispute.

Journalists at the London office based in the Shard building say they have not received a pay rise in years despite increased living costs.

“The talks have been going on since 2015 and members have been losing patience. They voted almost unanimously to go for strike action,” Frances Rafferty, campaigns and communications officer at the National Union of Journalists.

“It’s a last resort, they’ve tried negotiating and they are just completely frustrated, nobody wants to go on strike but they are in a position where it is an option of last resort.”

Al Jazeera English is headquartered in Doha but a significant number of its journalists work out of its London office, which is responsible for European news gathering, current affairs programming and live evening news output.

The strike will take place on May 9 and will be followed by “action short of a strike” in which there will be a “withdrawl of good will,” with staff starting to take their statutory meal breaks in full and refusing to answer telephone calls, emails and messages out of normal hours.

This will begin on May 10, 2018 and continue “indefinitely,” the NUJ said — but it could be suspended “if management is prepared to come back and start meaningful talks.”

Al Jazeera members of the NUJ and the Broadcasting, Entertainment, Communications and Theatre Union (BECTU) lodged a claim in 2015 over redundancy policy, expenses and overtime. While progress was made in some areas, the management rejected requests to negotiate over pay.

An email sent to Al Jazeera staff on Dec. 29, 2017 signed by the broadcaster’s London HR team said: “Al Jazeera Media Network (which includes Al Jazeera International London) will not be offering standard pay increase or bonus to global staff in 2018 due to global budgetary constraints.”

The email said 17 staff members “whose salaries fell below the minimum market rates” had received pay rises.

Commenting at the time, the Al Jazeera NUJ branch said: “We went into pay talks three years ago expecting to negotiate over percentages. In that time Al Jazeera management has refused to improve on 0 percent — effectively handing all its staff an annual pay cut, once inflation is taken into account. The ballot result shows our members are not prepared to accept this.”
