There are alot of people at work I would like to invite, but due to limitations i can not invite all of them, Should I just invite the ones who I have known longer or just my managers? And if so, Am I obligated to invite their Husband/wife?
I have already had so many people (who i wasnt planning on inviting) say they cant wait to go to the wedding!!! Help!

I would suggest if you have a close ring of coworkers I would invite them, without their significant other. Just explain to them that due to your budget you can only invite them and not their spouse. They will still have the other coworkers to hang out with at the wedding reception.
