I am putting together my guest list with my fiance and since we met at our previous job, we want to invite work friends. I was just wondering what the proper etiquette is regarding inviting work friends with spouses. We have never met the spouses of the people we worked with, so would it be rude to just invite the work friends minus their spouses? Or is it a rule of thumb to invite the work friends with their respective spouse? Thanks so much!
