Problem-Solving Case: Suspensions of Lexington, Kentucky, Police Officers

A police officer in Lexington, Kentucky, was troubled by content some other officers had posted on the MySpace.com networking Web site. These officers discussed their work, includ- ing arrests they had made. Their postings included put-downs such as slurs about gays and mentally disabled people and comments that they worked for Lexington’s “snobby peo- ple” and the “Lexington Fayette Urban Commu- nist [instead of County] Government.” Photos on these officers’ MySpace pages showed them in uniform. The officer who was disturbed by the content reported the sites to a supervisor. The supervi- sor pursued the complaints, and the police department sought guidance from Urban County’s law department, so that the officers’ First Amendment rights to free speech would be respected. A board of police and law officials met privately to review the officers’ conduct and recommend appropriate discipline. The board recommended to Lexington’s police chief, Anthony Beatty, that five officers be charged with conduct unbecoming an officer, be suspended for 80 hours without pay, and receive additional sensitivity training beyond the training routinely given to all Lexington’s police officers. Police Chief Beatty accepted the recommendations and presented the plan for discipline to each of the officers. The officers accepted their discipline. After completing their suspension, they were to return to full-duty status. Beatty told a reporter, “In my discussions [with the officers] we certainly have talked about getting this behind us, moving on and making us an even better agency and enhancing our relationship with the community that we serve. And all of the officers are commit- ted to doing just that and are very remorseful for what happened.”

Questions –

1. Was it appropriate for the police department to discipline the officers for behavior that took place outside their jobs? Why or why not?



2. If you had been the supervisor who received the complaint about the officers’ MySpace postings, how would you have reacted? Whom would you talk to, and what would you ask?



3. Overall, as described here, does this case provide an example of effective discipline? Can you suggest a few ways a police department supervisor could add to the effectiveness of the discipline in this situation? (Keep in mind that government agencies, such as this police department, often have to follow strict procedures for documentation and decision making.)

Question 2 options:

A company decided to expand, so it opened a factory, generating 455 jobs.

• For the white-collar positions, 200 males and 200 females applied. Of the females who applied, 20% were hired, while only 15% of the males were hired.
