Union activists expect “the vast majority” of schools in Doncaster to close, as council employees in the public sector union Unison prepare to strike alongside teachers on 30 June.
Unison is striking against budget cuts and job losses at the council and could take further action later in the summer.
Unison branch secretary Jim Board said ““It is a one day strike, and there will be widespread disruption to council services across the board. We will be looking at possible further action throughout the summer, as we have authorisation for continuous and escalating industrial action.”
Doncaster’s NUT branch secretary John Coward said: “I think if Unison are coming out as well as the NUT and ATL, it is likely most Doncaster schools will be closed. Had it been just the two teachers’ unions I think we would have been looking at a quarter of secondary schools and about half the primary schools.
“A lot of the site managers who open the buildings are in Unison.”
