Texting etiquette between coworkers is a weird science that nobody has truly mastered. Professionalism is an admirable goal, but act too professional, and you can come off as stiff and unlikeable to your colleagues. Generally, a good rule of thumb is to start as professional as possible and read the room, gauging the vibe of different coworkers. However, not everyone will be satisfied with your communication style, as some people are still firmly in the 1800s regarding workplace etiquette.
