TOPEKA, Kan. (AP) — An employees union has received complaints that high-level managers kept some Kansas psychiatric hospital employees from receiving superior ratings on annual performance reviews. The Topeka Capital-Journal reports that the Kansas Organization of State Employees says it received complaints from three workers at Larned State Hospital, which has struggled with staffing shortages. The workers told the union that that their hospital supervisors rated them "exceptional" but that those determinations were overruled by central office administrators at the Kansas Department for Aging and Disability Services. The employee union's executive director, Rebecca Proctor, says two mid-level hospital supervisors reported executives at KDADS were responsible for lowering staff ratings. KDADS secretary Tim Keck said he hadn't issued a directive to low-ball annual evaluation scores. He says that would undermine employee relations.
