That is how I am set up. I have two accounts. All of my work contacts are prefixed with the company name so they are neatly arranged inside of my contacts.
Ex:
DF cr6
DF dfman
DF Ollie
It stacks them nicely so they aren't scattered out inside of my personal contacts.

I am assuming that you have one account containing your personal contacts and one account containing your work contacts.
If you are log into one account now, how do you switch account when you want to see and use the contacts of the other account?
If one of the account is the primary account that you setup the phone, how do you see and use the contacts of the other account without factory reset?
