I work for a well known worldwide bank. My department however is fairly small (16 people) and everyone is fairly tight-knot as they have worked together most of them for many years. However, I have only been here for 3 months and am not that close with any of my co-workers yet. We are all friendly enough and they know I am engaged and a few of them ask questions about my wedding planning from time to time. I know it will be awkward if I don't do some type of invitation for them, but at the same time I am not going to send out 16 individual invites to their homes because that honestly would probably be more awkward than not inviting them, as I said I am not close too them and some I barely even speak too! I'm also getting married back home (2 states away) and I know none of them will come. Is it okay to just send an office invitation that includes everyone? My fiancé and I plan to have a reception later on back here as well for his family and friends that can't travel either, so should I send an office invitation for that as well? We are getting married in 3 months and are about to send out our invitations so I'm stuck on what to do.
