People often do things they enjoy when connecting with others, tlhinking that is what others need–especially extroverts and mostly when they aren’t self-aware. e.g. when my wife heads out with friends she tries to plan things for me to do (or even friend hangouts) so I won’t be bored. But that is her as an extrovert thinking how she would be if I went out. I have to reexplain each time that I won’t be bored–i will catch up on reading, podcasts, bike ride, etc, enjoy some solitude, and if I felt the need then I would reach out to a friends.
You may need to have a candid chat and explain that as an introvert you need quiet alone time to recharge your battery–while extroverts charge their battery by being busy or outgoing.
I had the luck of working at two places where HR took the real meaning of Human Resources to heart. One place saw their role as maintaining the “resources” in good stead like they would for their machines or tooling, since a broken resource can’t further your company goals. They offeres check-ins to see how things were going, any gripes, any way to spread workload.
Current one has been great too. I had one employee being quite toxic about other employees as an odd way to create internal allegiences and it was creating a difficult situation. I talked with HR rep and they took care of it. That employee now acts professionally.
Sometimes HR is OK, but read the company culture first
