The OSBA will file papers this week to help defend against a lawsuit against Senate Bill 822.
It's the only PERS reform that passed the legislature this year.
Alex Pulaski with the OSBA says school districts across the state are seeing shrinking dollars in the classroom because of the Public Employees Retirement System.
"As you look around the state, we've got the shortest school years. We have the third highest class sizes in the country and it's a direct result of the high cost of PERS. We believe these employees deserve a fair retirement, but the pendulum has swung and we feel it has to swing back."
This week the OSBA will file papers with the State Supreme Court asking they be allowed to intervene in the litigation. They want to help defend against the effort to get rid of the PERS reform passed this year.
