Cleaners at the School of Oriental and African Studies (Soas) in London were set to protest on Thursday of this week against their employer, outsourcing giant ISS.
The Unison union members are in a long-running battle for better conditions for the migrant workers who make up the workforce.
Recently the company announced that new vacancies will not be given to cleaning staff already employed in Soas. ISS also demands that new staff must be fluent in English.
Most of the Soas cleaners are not fluent in English but have worked there for many years, some for 18 years.
The cleaners argue ISS should provide lessons for workers rather than refuse to hire non-English speakers.
They are also opposing the company’s attempt to hire new staff on worse terms and conditions.
This move violates an agreement reached last year that won improved sick pay, holidays and pensions after a series of solid strikes.
The cleaners, their union and their supporters have pledged to resist the introduction of a two-tier workforce.
