A recent Well blog post about bullies in the workplace generated more than 300 reader comments, prompting me to explore the issue further in my Well column in Science Times this week.

Bullying in the workplace is incredibly common — a recent survey suggests more than one-third of employees have been bullied on the job. The problem is that the tactics used by workplace bullies usually are insidious and difficult to complain about. Often, the only way the bullying stops is when the victim quits.

Here’s a Workplace Aggression Research Questionnaire developed by researchers from the State University of New York in New Paltz and Wayne State University that identifies these often subtle bullying behaviors. Take the quiz to find out if you’re a victim of bullying. Occasional insults don’t count. Bullying occurs when the behavior has occurred consistently during the past six months.

In the past six months have you regularly:

Been glared at in a hostile manner?

Been excluded from work-related social gatherings?

Had others storm out of the work area when you entered?

Had others consistently arrive late for meetings that you called?

Been given the “silent treatment”?

Not been given the praise for which you felt entitled?

Been treated in a rude or disrespectful manner?

Had others refuse your requests for assistance?

Had others fail to deny false rumors about you?

Been given little or no feedback about your performance?

Had others delay action on matters that were important to you?

Been yelled at or shouted at in a hostile manner?

Been subjected to negative comments about your intelligence or competence?

Had others consistently fail to return your telephone calls or respond to your memos or e-mail?

Had your contributions ignored by others?

Had someone interfere with your work activities?

Been subjected to mean pranks?

Been lied to?

Had others fail to give you information that you really needed?

Been denied a raise or promotion without being given a valid reason?

Been subjected to derogatory name calling?

Been the target of rumors or gossip?

Shown little empathy or sympathy when you were having a tough time?

Had co-workers fail to defend your plans or ideas to others?

Been given unreasonable workloads or deadlines — more than others?

Had others destroy or needlessly take resources that you needed to do your job?

Been accused of deliberately making an error?

Been subjected to temper tantrums when disagreeing with someone?

Been prevented from expressing yourself (for example, interrupted when speaking)?

Had attempts made to turn other employees against you?

Had someone flaunt his or her status or treat you in a condescending manner?

Had someone else take credit for your work or ideas?

Been reprimanded or “put down” in front of others?
