[Co-Worker's Name] has been a part of our team for approximately [duration] and, unfortunately, their conduct has been increasingly problematic over the past few months. It has become quite challenging to work in an environment where professionalism and mutual respect are disregarded. One of the primary issues is [Co-Worker's Name]'s consistent disregard for deadlines and project timelines.
