We all work or will work in our jobs with many different kinds of people. What are some important characters of a coworker

Nowadays a large number of people are workers; they work together in workplaces and get close with many different people from different places, often becoming friends also. It is human nature that where a person works, studies or lives they get close to people ambient to them. Some coworkers are better to be a friends with; they have a good nature. However, there are also some coworkers who are are different in nature and their characters are worse, which shows their aggressive behavior. So, in my opinion, there could be different kinds of people whom we admire or get irritated with depending on their qualities.
Nobody wants to work with coworkers with an opposite ideology. I don’t want to work with a dishonest colleague who would be an obstruction in my working life. He may be a liar, he can complain about me, and also create gossip about me in the work place. It is a very bad character of a coworker to share anyone’s confidential secret. The bad coworker will now be unreliable and other coworkers will keep their distance, which is not good for the workplace. These are the bad characteristics of a coworker that I don’t want in my working life.
