More than 150 additional employees have accepted buyout offers from the private Philadelphia institution. Drexel University plans to lay off 60 staff members as it tries to balance its budget. The cuts do not apply to faculty and represent less than 1.4% of the private, Philadelphia-based institution’s workforce, according to an emailed statement from the university. Another 155 employees have opted into the university voluntary retirement incentive program, according to Drexel.
