The majority of schools in Hounslow are likely to be closed or partially closed during a national strike this Thursday (July 10), a union leader has said.
Teachers are joining council staff, firefighters and health workers for what is expected to be the biggest public sector walk-out since 2010.
Unions including the NUT (National Union of Teachers), FBU (Fire Brigades Union), Unison, Unite and GMB have all voted to take part in the industrial action over pay.
They will be protesting at the one per cent cap on public sector pay rises, which has been in place since 2012, following a two-year freeze.
Marilyn Bater, secretary of Hounslow NUT, said: "We don't have exact numbers at this stage but several reps have told me their schools will be closed, and the majority are likely to be partially closed."
She added that the impact was likely to be slightly less than that of the last NUT strike in March, when she claimed 92 per cent of schools in the borough were closed or partially closed, though the council put the figure closer to 80 per cent.
She said that was because teachers were reluctant to cancel school trips, which are common at the end of the summer term, given parents have already paid and arrangements have been made.
Kingsley Academy, in Hounslow, has already confirmed it will be closed this Thursday, while the headteacher of Gumley House Convent School, in Isleworth, has written to let parents know there will be no lessons for pupils in years seven, eight and 10. Lampton School, in Hounslow, has said it expects to be open as normal.
The strike is also expected to affect council services, though neither the council nor the relevant unions have yet said what they expect the impact to be.
A council spokesman has told getwestlondon that, as with previous strikes, it will ensure urgent services for the most vulnerable residents continue as normal on the day.
