Summa Health System is eliminating premium pay for about 230 nurses who work weekend shifts at Akron City, St. Thomas, Barberton and Wadsworth-Rittman hospitals. The nurses recently were notified that they will no longer receive bonus pay for working weekends beginning June 29, Summa spokesman Mike Bernstein said Monday. "Based on current compensation models at similar organizations in our market, we have adjusted our nursing compensation as related to premium pay for weekend hours worked," Bernstein said. "No changes have been made to anyone's base pay. … We did not announce a reduction in hours for the nurses in question, and we did not make any changes to care at the bedside."
