Teachers in the NUT and NASUWT unions in Tamworth, Staffordshire, continued their campaign against a proposed academy in the town with strikes and a mass lobby of a council meeting last week.
The academy would take on all sixth-form teaching in the area and lead to the closure of existing sixth forms, which would threaten around 70 jobs.
Workers at five schools have been taking part in a programme of rolling strike action in opposition to the plans. They have won widespread support from the local community.
Workers at Belgrave High School struck on Wednesday of last week, while those at Queen Elizabeth Mercian School and Rawlett Community Sports College struck the day after.
Teachers at Woodhouse Business and Enterprise College and Wilnecote School struck two weeks ago.
