A looming strike by oil workers in the North Sea could “severely disrupt” UK fuel supplies, the Unite union has said, adding that staff were left with no choice after a breakdown in pay talks with the Texas oil company Apache.

The union said Apache workers had “emphatically” backed strike action after being given what it said was an unacceptable pay offer that amounted to a real-terms pay cut for many employees, at a time when the company was “raking in eye-watering profits”.
