(Salem, OR) -- Oregon's largest union of state workers is calling on the legislature to help fill nine-thousand vacant positions. SEIU says the vacancies caused employees to work 150-thousand hours of overtime in the first nine months of last year. They say it's affecting the performance of all state agencies. They want the legislature to boost funding for pay which would help keep employees from leaving and help with recruitment. SEIU's contract with the state expires on June 30th.
