Brief guidance on Working to Contract issues. This is taken from item 24 on the FAQ page: https://www.ucu.org.uk/heactionfaqs
What should I tell my employer if they ask if I am participating in action relating to working to contract and to the maximum 37-hour week?
You should wait until you are asked by your manager or a person in authority whether you are participating in ‘action short of a strike’ and then answer as follows:
As you will be aware, following a recent ballot, UCU is calling on its members to take continuous action short of strike from 27 May 2016. This is to take the form of working to contract. I am writing to inform you that I shall be working the hours stipulated in my contract and no more. Where my contract is silent on the hours I am expected to work, I will work no more than a total of 35 hours per week, or my pro rata equivalent to take account of my personal circumstances and the length of the normal working week in question. In addition, I will perform no additional voluntary duties, such as out of hours cover, or covering for colleagues, unless this is a contractual requirement, nor will I set and mark work beyond that which I am contractually obliged to set and/or mark, nor will I attend meetings where attendance is voluntary. I will not undertake duties that breach the University’s health and safety and I will work strictly in accordance with the university’s policies or procedures having contractual force.
As I will therefore complete my contractual duties on a weekly basis and in any one week I will not expect the University to make any deductions from my salary save in respect of any strike action which I might take. I will raise a formal grievance if I am deducted pay whilst I am working in accordance with my contract.
