How do co-workers affect employee behavior?

If we like who we work with, chances are, we will like where we work. Co-workers' behaviors, whether negative or positive, have an influence on employees' behaviors. While co-workers' positive behaviors can influence an employee to "pay if forward," encouraging others and promoting a positive, effective and productive workplace, negative behaviors can really put a crimp in our day. Negative co-workers might cause an employee to grow to hate their job, skip work, zone out or just plain quit.

If co-workers are honest then it will be easy for anyone to remain honest; Conversely if co-workers are then it will be difficult to work with full honesty. It's a one example, there are millions of them.
