I manage a small team of myself and 2 others. The other software engineering teams at my organization tend to all get along and interact with each other socially a lot, while my team members are excluded.
For example, an employee recently left the company and the other teams in my department all took them out to a farewell lunch. My team was not invited.
I'm a bit more of a introvert and less concerned that I personally was not invited, but I worry about my team members becoming demoralized since they were not included.
What can I do to help my team feel more included?
