A “devout Christian” who says she was singled out by co-workers for teasing and harassment because of her attitudes about sex — and that management did nothing to stop the teasing when she complained — has filed suit against Toppers Salon and Health Spa Inc.

Attorney Michael J. McCaney Jr. of Pennsylvania’s Flamm Boroff & Bacine filed the suit on behalf of Kathleen Mullen, a manicurist and esthetician who started working for Toppers in April 1997.
