Dear X,
I understand that the University has made or intends to make deductions from my salary due to my participation in the UCU marking and assessment boycott. I am writing to inform you that I am no longer participating in the UCU Marking and Assessment boycott.
My involvement in the marking and assessment boycott ended on (date that you ended your involvement in the boycott, for example the day after your marking was reallocated or the day after the assessment deadline).
Kind regards,
