How to invite my co-workers to my baby shower?

My mom and mother in law are planning it but Im in charge of the invites/who to invite.

Id like to invite several girls from my job but rather than giving everyone there an invitation and singling people out, I thought of just hanging one up with a special note that anyone can attend (which I know they *all* wont).

OR should I take an invite and write a few names on it and then put "plus whoever else wants to attend".  For example, I really dont want to invite my boss but I dont want her to feel left out either.  If I give it to each one in private I know theyll ask the next girl if shes going lol.. ugh would if that persons not invited? Awkward!
