There has been significant work in journals that say job strain occurs when you are subjected to high task-demand and low controls, which is as significant a health risk as smoking. But people don't want to hear that the workplace is a killing field. The post office provides the ideal circumstance for bullies. Postal workers are set up for failure by demands to speed up until they can't keep the pace. They are guaranteed for failure, allowing the tyrant to come in and bark.
Targets turn inside out trying to do what the boss wants.
In one report, one in three postal workers experiences verbal abuse. The Namies hope their campaign will break through the corporate mindset so employers can understand how bullies take human and financial tolls on the workplace. They cause good employees to seek other jobs, creates illness, kills morale and eventually hurt profits. There's nothing bullish about bullies. Legislation might be years away, but they feel the bully's days are numbered.
