Workplace socializing can feel stressful because it sits between professional expectations and personal behavior. You’re not fully relaxed like with friends, but you also can’t be completely formal all the time, so there’s constant self-monitoring.
There’s also the fear of judgment. People worry about saying the wrong thing, being seen as unprofessional, or damaging how others perceive their competence. On top of that, office dynamics, hierarchy, and unspoken politics can make even casual conversations feel loaded.
I think there is also another reason. After focusing on tasks, social interaction can feel like extra work, especially for introverted people. So it’s not just talking, it’s managing impressions, tone, timing, and relationships all at once, which naturally creates pressure.
