On Friday afternoon came a big push from the District 46 teachers union to stand unified for a contract agreement.
Teachers, along with some parents and students, lined Route 83 between the district offices at Frederick School and Grayslake Middle School.
The Queen song "We Will Rock You" could be heard blaring from a stereo on the picket line as passing vehicles honked loudly and picketeres erupted into cheer.
Students have been out of school for three days. The District 46 Board of Education and teachers' union have scheduled another negotiating session for 5 p.m. Sunday at Park School.
Parents who walked the picket line with teachers told Patch they plan to be present outside Park School on Sunday to show their support for the teachers, who have been without a contract since July 2012.
"We love our teachers," said parent Debbie Peters, who has two students at Park School. "I am behind them 100 percent. They deserve a raise. They are with my children more than I am. I'm very proud of the teachers for standing their ground."
Another parent told Patch she believes the strike will continue into next week but that she supports the teachers.
"I think we have a really good group of teachers and it would be sad to see them go," said the parent, who did not want her name used.
