American Federation of Teachers, Local 691 v.
Kansas City School District, Kansas City, Missouri
AFT filed a petition to represent Security Officers employed by the School District. The Board found that the Security Officers were Watchmen, not police. They do not have authority to enforce the law by means of arrest, nor may they carry firearms.
The Board also said that it was not against public policy to allow a union to represent both Guards and Non-Guards, so long as they are not in the same unit.
