Public employees may not influence or give money, services, or other things of value to promote or oppose the nomination of a candidate, the gathering of signatures on a referendum or petition, the adoption of a measure, or the recall of a public office holder. Public employees may not engage in these activities either independently or under coercion from another. Public employers must post a notice in a conspicuous place to this effect (OR Rev. Stat. Sec. 260.432).
