Oxfam charity workers have secured an improved pay award following the organisation's first-ever strike.

The majority of workers secured six per cent pay increase and lump-sum payments of £2,300, after two days of industrial action on December 8 and 9.

The majority of Oxfam's staff joined forces with Unite members to participate in the industrial action, which also resulted in significant commitments from Oxfam.

Unite general secretary Sharon Graham said: "Unite’s Oxfam members are to be congratulated in their refusal to back down and their refusal to take no for an answer.

"Their hard-fought campaign has resulted in an improved pay offer, an improved lump-sum payment and better terms and conditions.

"Yet again, this shows there is power in a union."

Key improvements include the introduction of better minimum wage, pay progression, improved recognition for Unite, and assurances that striking workers will not be discriminated against.

Unite's regional coordinating officer Jamie Major said: "Oxfam thought it could trade on its charitable status to make a poor pay offer.

"Our members took the fight to the picket line to make their strength of feeling clear.

"I’m delighted they have secured an improved offer."

As part of the agreement, Oxfam and Unite will work together to investigate the impact of rising cost of living, protect real incomes, and develop new benchmarks for minimum wages.
