Workers employed by OCS to clean British Airways offices and buildings across four terminals at Heathrow are set to strike this Christmas over low pay.

Strikes will take place from today, December 18, to December 29.

Staff involved in the dispute, consisting of more than 80 Unite members, are currently paid the minimum wage of £12.21 per hour.

Since early last year, workers have been asking for the London Living Wage, an independently calculated hourly rate reflecting London's high cost of living, which is £14.80 per hour.

Their counterparts on the Mitie contract at Heathrow, who do similar roles, are paid the London Living Wage.

In the UK and Ireland, OCS has an annual turnover of around £1.7billion which the facilities services provider aims to double within five years.

Meanwhile, British Airways made a profit before tax of £896million in the first half of 2025 and CEO Sean Doyle received a £2.1million bonus in May this year.

As well as offices, including BA's Waterside head office, workers clean cargo and engineering hangars where planes are repaired…
