Someone talk me down please...I taught two modules this year on a one day masters. One was timetabled 9.30 to 12.30 and one 4 to 6. With agreement from the students, we had no break on the 4 to 6 module and would end around 5.40. I would always come early (they had a break 30 minutes beforehand) for any chat or Q&A and start the lecture bang on 4pm. It was a new module (for me) and I tend to be quite fast at getting through slides so had to add additional content. Student feedback was excellent and all did well in their first assessment.
One student was tricky and as the term progressed was clearly having psychiatric and family issues. I did support him and put him in contact with student services.
He has now withdrawn and is making a formal complaint about me ending early so he can get a full refund on fees because we did not provide the service he paid for. He has engaged a solicitor.
What can I do? Is this the sort of thing that gets a formal disciplinary?
