Authorities at the Tomah VA medical center are investigating another report of misconduct.
Acting director Victoria Brahms emailed employees, saying that a hospital employee reported being a victim of inappropriate contact by another worker.
Brahms also says that reassignments have been made.
Last week, a mental health worker at the VA was charged with sexual exploitation by a therapist.
The facility has also been under investigation for reports that physicians over-prescribed painkillers.
