Department for Education’s workload reduction toolkit
As workload can be a key cause of additional pressure for staff, the DfE’s Workload Reduction Toolkit may be of use to teams wishing to do workshops around managing workload for staff who may be feeling overwhelmed by increased pressure: https://www.gov.uk/guidance/school-workload-reduction-toolkit.
It also contains a section on Wellbeing and workload reduction, with suggestions for things staff can do, eg. action plans and WSA examples. Some practical resources and tools are available here to support staff about teaching mental wellbeing: https://www.gov.uk/guidance/teaching-about-mental-wellbeing.
