The City agrees to furnish, maintain, and locate bulletin boards in each station, bureau, shop and office for the use of the Union to post notices relative to legitimate Union affairs. Articles posted on these organizational boards should be approved by an authorized representative of Local #92. The City or its representatives shall maintain the right to remove materials which are unauthorized and/or extremely distasteful or disruptive, e.g., racially or sexually motivated articles, comments, or pictures. Materials removed by the City representative are to be turned over to Local #92 at the earliest possible date. Prior to the removal of these materials, (when practicable) a Local #92 representative shall be notified.
