Outlet with ground wire attached to socket ground and neutral
Misusing ground as neutral is a code violation.  It's the work of a hack electrician trying to get a job across the finish line, or other tradesman who severed a neutral by accident and hacked it so no one would notice. 

I would search each receptacle box in that circuit for a reason for a neutral problem. Most wiring problems are at terminations.  If you find none, I would find the next box back on the cable run (that is still hot), and disconnect the cable there. Whatever broke the neutral may have also nicked the hot.  

If the electrician did this, then every connection in your house needs review.  You know how to do receptacles!
