I'm a TA at a British university, and as part of this job role I create and write educational material, which also includes creating and marking assignments.
I've recently discovered that several of the assignments I wrote have been taken by a colleague, my name then scrubbed off them, and distributed as part of this colleague's assessment strategy. My colleague did not tell me he was going to do this, and I feel as though my hard work has been/could be unfairly attributed to my colleague.
I feel aggrieved by the situation, but am I being unreasonable before I decide to escalate this matter?
