Do coworkers get a plus one?

Plus ones are for single guests only. They’re not required. Couples should be invited together by name. It would be extremely rude to exclude their significant others, married or not.

Originally I did not have enough in my budget to give my coworkers plus 1's. I asked if they would be upset if I could only invite them with no plus 1, and they did not mind and understood.

We ended up with some additional funding & I was able to give my coworkers a plus one, I figured it's best because they won't know many people at the wedding. I'm only inviting about 3 coworkers though.

If I was invited to a wedding and my fh was not invited I would not go. I would be careful about having the you are invited but your husband is not conversation. People get offended so easily. Most times it is assumed that if they are married the invite is to both people. Anyone who is single it is your choice unless it is a serious boyfriend.

Yeah that would be tacky and quite rude. Sorry but it just is

Although ettiquite says it is rude, I'm going to go out on a limb here only because you want to invite ALL of them. I would tell them of the situation. You want them there, they know each other, but unfortunately there isn't space for them to bring husbands or SO's. If you keep them at the same table or two tables I don't think it would be bad.

Now if it's a matter of budget and not space, don't do it.

So most people are firm that this is tacky/rude.. but i disagree to an extent. here's my experience:
I have been working in my office for about 4 years and a group of 10 of us are pretty close.
3 of the 10 have gotten married over the past few years, and for their weddings they invited co-workers without their spouses (even if they are married). All the women came stag and we had a blast! No one was offended. To be honest, most of us haven't met each other's husbands.. and if we have it's been a brief encounter. My mom thought it was crazy that people were going to these weddings without their husbands, but I think heck... why not! Girls night out. Honestly I think it depends on your group at work. At mine, the precedent is now set and I will also be inviting the ladies stag to mine .

I agree with D above. You could ask and describe the situation of limited space. I know for coworkers people don't necessarily do the plus one deal because they can all sit together but with husbands it gets tricky. I still think it would be okay if you are really stretching your venue space. Some might be fine with it and some might feel weird.

In my opinion, if you invite someone with a significant other, the SO should also be invited.

If they're part of a couple, the other person needs to be invited by name, not just as a "plus one". Those that are truly single do not need to be extended a plus one.

I was told that anyone who is married or in a serious relationship is supposed to get a plus one. Some of my married coworkers asked to bring a friend/ sibling/etc in place of their spouse and I allowed that also so everyone feels comfortable.
