Teachers at a private boarding school in north Nottinghamshire have voted to strike for "several days" later this month to protect their current pension scheme.
National Education Union members at Worksop College and Ranby House have voted for several days of strike action from April 20.
Teaching staff have been angered by the school's decision to opt out of the national Teachers' Pension Scheme (TPS).
Staff and parents were left shocked when the school informed them that they were pulling out of the TPS and arranging for staff to go into an "inferior scheme".
The union has said this will mean employees will lose out on thousands of pounds in retirement.
The boarding school explained it could not meet the mandatory increase of the TPS announced in 2019, against the impact of the pandemic and a consultation process was underway to discuss next steps for individuals.
The NEU said it has looked to settle the concerns but union members will now take industrial action.
The NEU believes the school has not properly consulted staff and has not considered how these changes could endanger the future for the provider in attracting teachers into roles.
Nick Raine, Senior Regional Officer with the NEU said: “Worksop College is a respected and trusted school with excellent outcomes for its pupils.
"Those outcomes are achieved by highly qualified, experienced and committed teachers. Those teachers’ terms and conditions are now being viciously attacked.
"The huge cuts to teachers’ pensions will sadly force many teachers to consider their future and moving elsewhere. Our members are fighting for the future of the school.
"Staff are angry that the College will not meet with their union or listen to their concerns about the direction of the College. That Worksop College has forced our members to take this step demonstrates that they don’t care for staff and are not being honest with parents as to the future of the school.
"We remain committed to negotiating a solution to secure the future of the College. The NEU remains committed to negotiating a settlement but cannot do so will the College refuses to meet with us."
In a previous statement from Worksop College, a spokesperson for Penny Owston, chair of governors said the school was "unable to support increased pension contributions and the financial impact of Covid".
Existing staff were given an uplift in their pension from the level they were at in 2019 but not the same 40 percent increase mandatory in the TPS.
The statement added: “We are very respectful of the rights of teachers to take industrial action. If that is what they choose to do, then we have to accept that and put in place plans to manage it. I am sure that nobody would want our children to miss further schooling, so in the event of any decision, we will do all that we can to keep our children learning."
“Our staff are a fantastic group of people who want the best for our students, but understandably also have their own futures to consider. We share their desire to recognise their contribution – but we need to balance that and ensure our school has a long and successful future."
