I am an introvert who works in Marketing; however my role currently involves primarily working with our website. If I have no meetings, technically I could literally get through the day without talking to anyone. That said, I do communicate when I need to, but tend to avoid the chit chat. I actually plug in and listen to music most of my day so that I don't have to hear everything that is going on around me.

My thought is don't worry about making chit chat. Be friendly and courteous, but you don't have to stick around to chit chat. During break times, go for a walk instead, or read, or do something that you enjoy. When actually working, just make it apparent that you are doing your job and communicate as much as you need to, to do it well.

I will say this, managers have more appreciation for people who do their job, than those who spend a lot of time with the chit chat. It might not seem like it some time, but in most cases, unless the manager is totally inept, that really is the way it is. Just be yourself.

And by the way -- I'd enjoy working with you I think. I work with way too many people who spend more time visiting than working.
