I had a coworker that worked in the company for 14 years. Since the day I started working, she did nothing the entire time but talk to other coworkers and sit on her phone. She had no communication and wasn’t responsive to any reprimands. My manager would always ask me to give her an update of how she was doing because I worked on the same team as her. She would also cause problems with other coworkers. I personally believe that everyone deep down inside is good and has a good work ethic. It is tough circumstances in life that sometimes force some people to act the way they do. Some people have had such a hard life that they don’t care about anything anymore. She was one of those people and nobody knew it. To deal with people like this, you have to “kill them with kindness” so to say. You have to be nice and genuine and caring with them and develop that personal relationship. Once you do that, they will enjoy working and not feel the burden anymore. This is how we handled her and she improved dramatically after doing so.
