One of my friends, a relatively recent grad, has been working at a hospital for about a year now and hates her co-workers. She complains about how "catty" her co-workers are.
One the flip side:
One of my aunts has been a nurse for about 20 years now and loves her co-workers at the hospital she works at but always complains about how the supervisors are breathing down her neck and she feels like she has to walk on eggshells.
