More than 600 Border Force workers at Heathrow Airport will strike for four days in April.

The PCS union has announced workers who carry out immigration and passport checks voted by 90% in favour of walking out over new rosters and imposed changes to shift patterns.

The union said the changes meant 250 staff could lose their jobs by the end of next month.

Strike action will take place from 11-14 April.

PCS General Secretary Fran Heathcote said: “Ministers have 14 days to withdraw these unfair and unnecessary proposals or our members at Heathrow will take strike action.

“Consultation with staff has been a farce, with our members having little or no choice about the new arrangements.”
