You should tell your students this:
From 10 October, I will be taking industrial action because my employer has refused to negotiate pension changes with my trade union, UCU. The changes have been rejected by more than 90% of staff but were still imposed. Future university staff stand to lose hundreds of thousands of pounds as a result while people like me will pay more, work longer and receive lower benefits.
The industrial action starts with me ‘working to contract’ which means that while I will not be doing extra work beyond that required, I will continue to do my best to support students. If this action does not persuade the employers to restart negotiations, my union will call rolling strikes and these will unfortunately undoubtedly mean disruption.
If you want to support our cause please contact the Vice Chancellor and ask them to publicly call for a resumption of negotiations.
