Allow visitors to use same email

I'm trying to find out if it possible to allow visitors to use the same email. The reason behind this is because some of the users at my office do not have an email address. Their manager is the one to receive all important information for them. Basically is there an "easy" way to way to make it where one email can be used for multiple people? PS Yes I know the absolute easiest solution would be to just create email accounts for them, however my boss would prefer the ticket information go to the managers etc.
