missing stair

informal Someone in a group or community whose troublesome nature or behavior is well known but not addressed or dealt with directly. The imagery of a broken staircase is used to highlight how people use warnings as an ineffective means of dealing with certain problems that ultimately and should be fixed. Coined by blogger Cliff Pervocracy in 2012. Those who sexually harass others will no longer be treated like missing stairs in our company. This means that instances of misconduct are to be reported to HR immediately.
