Teachers from the Lawrence School District rallied on Sunday to get officials to resolve a contract-negotiation impasse that has gone on for 12 years.

Teachers at the rally said a main sticking point is the school board’s demand to eliminate the class size cap.

“We have a class size provision where the Board of Education would like that eliminated from our contract. Studies show that having a smaller class size truly enables students to perform better and their outcomes are better. We refuse to give up on class size,” said Rachel Kreiss, of the Lawrence Teachers Association.

Kreiss, who has been teaching in the district for 22 years, believes it is time that educators receive a fair contract.

“We work hard every single day. We really do,” she said.

Lori Skonberg recently retired after 29 years of teaching in the district. She said teachers are also asking for a raise, which they haven't had in 12 years.

“They want more productivity and more teaching for less pay,” she said.

The last time teachers and the school district met for negotiations was last December.

The Lawrence Teachers Association has filed a lawsuit against the school board alleging bad faith negotiations.

News 12 Long Island called the superintendent of the Lawrence School District for comment but did not hear back as of Sunday evening.
