"Those same sources also say nearly 100 people have quit in the past several years," WIS TV reported on its website.
David Arnold, director of a crisis management group for first responders called Debrief Incorporated, called Mr Bronson's words "absolutely appalling".
"To say that to first responders who deal with death and crisis situations every day was not only insensitive but it was unprofessional and it was childish," he said.
Mr Bronson has since apologised for his actions in an all-staff email, acknowledging his words were "insensitive".
"Those comments are my own and, while I regret them, I must live by them," he wrote.
"The disciplinary action I received was appropriate and the time I spent in the woodshed was both painful and appropriate."
He also addressed his casual reference to suicide, revealing a close family member commit suicide once he finished university.
"The pain of losing her in that matter is deep and everlasting," he said.
"I should not have allowed either the heat of the moment nor the situation to lead to a moment of such callousness."
