McKinley High School was one of the 50 schools across the state taking part in the "Work To The Rules" protest on Thursday.
It's a protest where teachers will spend a few hours before and after their official hours of work voicing their frustrations regarding current contract negotiations.
The initial protest was held at Campbell High School with more than 600 teachers and students participating in that protest.
This was the scene at Aiea High School on Thursday. Last week, teachers pledged to continue the protest every Thursday for three weeks.
In the afternoon, Farrington High School students joined the protest.
Teachers and students lined King Street in front of the school and in front of Kamehameha Homes.
The intersection of King Street and Kalihi Street has a lot of traffic and many drivers saw the protesters Thursday afternoon.
