Staff at the University of Stirling are to begin a marking boycott from today.
Members of the UCU trade union are taking part in the action, in a dispute over pay, pensions and working conditions.
The union says it will continue until the dispute is settled.
A UCU statement says:
"The boycott will be carried out as part of both the pay and conditions and USS pensions dispute and will see staff cease all summative marking and associated assessment activities and duties (such as exam invigilation) until further notice.
The marking and assessment boycott will continue until the disputes are settled, or UCU calls off the boycott, or at the end of the industrial action ballot mandate."
