“I felt I was giving her life back,’’ Stevens told The Post. “My kidney ended up going to St. Louis, Missouri, and hers came from San Francisco.”

Stevens said she did not realize that she was in for serious pain, discomfort in her legs and digestive problems after the surgery on Aug. 10, 2011. She said she felt pressured to return to work Sept. 6, before she was ready — even while her boss was still recovering at home. When Stevens went home sick three days after her return, she said, Brucia actually called her from home to berate her.

“She . . . said, ‘What are you doing? Why aren’t you at work?’ I told her I didn’t feel good,’’ Stevens told The Post. “She said, ‘You can’t come and go as you please. People are going to think you’re getting special treatment.’ ”

After Brucia returned to work, she’d yell at Stevens in front of co-workers over alleged mistakes, Stevens said.
