'Lucifer' Star Rachael Harris Sued for Being a Devil Boss


Rachael Harris is an employer from hell who worked her nanny like a dog and then stiffed her out of more than a month's pay ... according to a lawsuit.  

Davy Salley-Rumph says in legal docs Harris -- who stars in "Lucifer" -- hired her to nanny her kid for 2 months. But Davy says Harris immediately showed her horns by cracking the whip with 12 to 24 hour days, 6 to 7 days a week ... without breaks or OT pay.

Davy says Harris committed a cardinal sin in early October when she fired Davy for no good reason, and then refused to pay her wages for the remaining five weeks of the deal.

She's suing for the back pay, plus penalties and interest. We've reached out to Rachael ... so far, no word back.
