Members of staff gathered outside of Castle School in Thornbury on Tuesday as they carried out their planned strike action.
They were supported by a number of students and parents at the school.
There were more strike days planned by staff, but after promising discussions between them and management these have been cancelled.
The Gazette was in attendance on the day but two Castle School sixth-form students captured the entire scene from the very beginning.
