Wednesday's official opening of the Liverpool King David's £25 million educational campus was called off because of the day of action by public sector employees over changes to pensions.
Chief Rabbi Lord Sacks had been due to be guest of honour at the ceremony for the state-of-the-art buildings which also serve as a community centre and conference venue for the Merseyside Jewish community.
He would have dedicated the school's synagogue, named after Tilly Rosenblatt, a former King David student who died of cancer. King David governor Lauren Lesin-Davies explained that "owing to the national strike, we were unable to staff the campus during the day and had to close the entire campus.
"We will definitely have an official opening in the not-too-distant future to celebrate this unique campus that has been such a catalyst in bringing together the entire Liverpool Jewish community."
