Ego When someone’s ego is more important than the team, the project, or the goal, things break down quickly. This can happen when one person is more interested in “looking good” for the boss than getting the work done, when someone is always placing blame, or when someone feels and acts like they are too good to do the necessary work.
Negative competition Lighthearted competition can be a good thing, especially for certain kinds of teams. In a sales team, for example, individual members can be motivated by gamifying their work with a leaderboard or bonuses for high performance. But when competition goes too far, it can destroy a sense of teamwork and create a “you versus me” atmosphere that isn’t good for anyone.
Poor communication When the left hand doesn’t know what the right hand is doing, it causes all sorts of problems: duplicate work, forgotten work, missed deadlines, etc. Communication is absolutely key to a team that works.
Micromanagement When employees have to get approval or sign-off on every single thing they do, it slows down the workflow considerably. Team leaders need to be able to trust employees to make the right choices, and employees need to feel comfortable asking for help when they need it. The right balance here is key.
