The FNV trade union and Albert Heijn supermarket group have reached agreement on a new pay and conditions agreement for delivery centre staff, a week after the union began taking industrial action.

The company has now agreed that people who worked regularly for the company on agency contracts will be offered a formal job after three years. This will benefit some 200 people, broadcaster Nos said.

The union is concerned at the high level of temporary employees at the centres. Albert Heijn says 2,000 of the 5,300 people who work at one of the six centres nation wide are on flexible contracts.

The company has also agreed to improve the redundancy package for staff who lose their jobs up to 2016.

The pay rise of 3.5%, accepted earlier by the CNV union, remains unchanged.

The revised agreement must still be approved by members.
