Union leaders have vowed to vigorously defend the jobs of EasyJet's 19,000 employees following the airline's acceptance of a £5.7 billion takeover offer from U.S. private equity firm Apollo.

The deal, which was accepted last week, has sparked speculation about potential changes for both customers and staff, with particular concern over possible cost-cutting measures that could impact job security.

Unite, a union representing thousands of EasyJet cabin crew, stated that it would exercise its full right to submit its views on the deal to regulators. The union has indicated that strike action could be a possibility if the deal does not meet their terms.

Sharon Graham, Unite general secretary, emphasized that while Apollo has stated it places a high value on people and retaining key staff, these statements need to be substantiated with action. "These warm words need to be translated into reality," Graham said. "Its growth strategy must translate into well-paid, unionised jobs, and existing roles must be protected."

Graham added, "Our members will always be our top priority at easyJet. Unite is committed to vigorously defending their jobs, pay and terms and conditions throughout the takeover and beyond."

Analysts have warned that the new ownership could usher in an era of cost-cutting for the budget airline. Experts suggest that EasyJet might increase revenue from ancillary charges, such as fees for luggage, seat selection, and onboard food and drink, similar to strategies employed by other low-cost carriers.

While Apollo's offer triumphed over that of rival bidder Castlelake, the transaction faces potential scrutiny from regulators. Reports indicate that the European Union is preparing to review ownership rules to prevent foreign investors from gaining control of companies. EasyJet's subsidiary in Austria, established to permit continued operation within the EU bloc after Brexit, could be relevant in this review.

If approved, EasyJet would join a growing list of British companies that have been acquired by foreign entities in recent months.
