I began a new job three weeks ago and am now wondering what I should do regarding inviting my new coworkers. My wedding is October 29 and so most of our guest list was done before I started my new job. There's about 25 people in my office, so there's no way I can invite all of them. However, there are 4 ladies who work in my department, that I see the most - would it be bad form to just invite my department and explain to anyone else who asks that I had limited space left??
