The Port of Felixstowe, Britain’s busiest container port, said that over 90% of its workers had agreed to accept a pay deal that would lift wages 8.5% in 2023.

The port, owned by a unit of CK Hutchison Holdings Ltd., will also pay workers a £1,000 ($1,230) bonus in the deal that is effective January 1, 2023, a spokesman for the port said in an email.

Workers at Felixstowe were among the first groups to strike in the summer over wages. Industrial action has subsequently spread into walkouts by postal workers, railway employees and even nurses and ambulance staff as wages fail to keep pace with the soaring cost of living.

Felixstowe said that this was the earliest it had concluded an agreement on the annual pay review.

“It provides welcome certainty and stability at a time when our employees, like everyone else, are facing an increase in the cost of living,” Robert Ashton, the chief operating officer of the port, said in the email.
