That really stinks AN.
I find the same at my full time job, in some departments.
I used to work in an area where my supervisor would come through the room and not even acknowledge me.
How do these people even get hired? We are in a billion dollar industry and the pays are in the high-income category. I would think a requirement for management would be the ability to MANAGE. I believe in building up your team, fostering an enjoyable, comfortable work environment where people feel at the very least content. I believe it makes for a good work place and it also makes productivity go up.
But no, many managers come in and act like children.
So no real advice, just feel your pain.
You are a friendly, out-going person, your job is to be customer-service orientated and I know you are. Let your joy be shared with those who appreciate you.
