Recently joined a new, small team at work. We're spread over 4 different locations and get together every month in person. Last time, I heard that 3 women (2 in equivalent jobs to me, and one at a grade below) in our team meet up at an office on a fairly regular basis but haven't invited me to join them. The junior team member joined about the same time as me but seems to have been taken under the wing of the others, whereas I've been very much left alone and not well supported to integrate into the team (along with another jr team member). I'm quite upset not to have been asked but perhaps I'm being over sensitive?
