Two Kansas University students who worked as house managers at the Lied Center say they think they were unfairly fired after raising concerns about their supervisor’s job performance.

Morgan Denton and Stefan Vogler said they took concerns to their boss Wednesday. Both were fired the following day.

The complaints were general, Denton said. They were concerned about the supervisor’s treatment of volunteer ushers, the lack of preparation for events and other matters.

Tim Van Leer, who is director of the Lied Center but not the students’ direct supervisor, confirmed the students were released from their duties, but he declined to elaborate on what he said was a personnel matter.

Denton and Vogler say they have called on the ushers to voice support for them to Van Leer. They plan to appeal their firing.
