Dozens of active and retired teachers are rallying in downtown Columbus this morning to complain about the state agency that oversees their pension plan. Many of the teachers walked from the Statehouse lawn to the State Teachers Retirement System building two blocks away to address the board at its monthly meeting. They're upset over reports that former executive director Herbert Dyer spent millions of dollars on bonuses, artwork and travel while assets plunged with the decline of the stock market. The teachers say even though Dyer has left, that isn't enough. Teachers and retirees are pleading with the board to curtail spending, limit travel and provide better health care coverage next year. The 47 (b) billion dollar retirement system protects 400-thousand active and retired teachers.
