Alexis commented with a guest list dilemma. She says:
Everywhere I have read, it seems that inviting people without inviting their significant others is a big no-no. We are trying to keep our wedding a small affair (less than 130) based on the fire-marshal code. Plenty of people that I work with have started assuming (and expressing) that they are invited to the wedding, so I have allowed for them in the count. However, I know very few of their significant others. Would it be rude to ask the co-workers to just come as a group (It’s not as if they wouldn’t know anyone else there…)? And if not, how would I word it if it came up in conversation?
The answer? Group invites aren’t proper etiquette, but they are common practice. Most offices wouldn’t frown on receiving a group invitation. However, keep in mind that you probably won’t get an accurate account of guests. If you need an exact head count (which it sounds like you do), go with separate invitations. If you are unable to invite the entire group because of space restrictions, then don’t invite anyone.
As for not inviting significant others, there is no way around this rule. If they are married or have a live-in partner, you need to invite them. It is up to your discretion whether you should invite a guest of the single co-workers. It’s a nice gesture, but not required.
