text: is it illegal to keep track of a co-workers time...? i work with a very annoying man who feels it is his responsibility to keep track of when i come and go. at the end of the day he tells my boss exactly when i arrived..took breaks..lunch..departed.. my boss said he has not asked him to do this. so how can i make him stop? is it illegal? not all harrasment is of a sexual nature. you could tell hr that you are uncomfortable with being followed oround. if its bothersome or makes you uncomfortable say so. if his obsession with you is accompanyed with personal attacks or critisisms say so. review your own companys policy on harrasment and how it is defined.  that is the kind of thing that just goes away if you ignore it. eventualy you boss will get sick of his behavior anyways.  or ( its a bad idea to do this but ) you can deal with it with a scence of humor and just start reporting to him and asking him questions he can't answer about the business. that some times can make a guy like that back off.
