How do I know whether I am contractually obliged to mark work or not?

In determining whether setting and marking given pieces of work are beyond your contractual obligations, you should ask yourself these questions

1. Is marking and setting work part of your job?
2. Is what you are being asked to set or mark consistent with your contract and your area of expertise?
3. Are you following to the letter the marking or second marking protocols in place in your department or institution?

 If you are doing (3) and are asked to speed up, respond that you are following your appropriate policies and procedures as laid out in your institution’s policies here. Ask your head of department or line manager to put in writing that they want you to speed up and request that they highlighting which parts of the protocols governing marking you should disregard.
