Grell is set to become the Executive Director of the Pennsylvania School Employees Retirement System.
According to Kevin Zwick of Capitolwire, Rep. Grell had issues with Speaker Turzai that contributed to his exit.
The soon-to-be former State Rep. served on the PSERS board but Turzai did not reappoint him because he was seen as too close to the labor unions. For instance, Grell opposed a plan to switch employees from a pension to a 401(k) system.
Grell has represented the 87th district since 2004. He sits on the House Judiciary, State Government, Insurance and Labor Relations Committee.
The 87th district is located in Cumberland County. There is no word yet on when a special election will take place.
