Execs at Tidal fired a new mother the day after she requested a private room to use her breast pump ... according to a new lawsuit.
Lisette Paulson says the music streaming company -- specifically Jay Z's trusted associate, Desiree Perez -- retaliated against her in 2015 for requesting a private pumping setup. According to her suit ... Perez told Paulson to just use a bathroom, but she said no way.
Perez allegedly asked the new mom if the pumping was really necessary and grew frustrated about having to give up a private office for Paulson to do her business. She says Perez told her they'd have a meeting to figure it out, but the day after that meeting ... Paulson says she was fired.
She's suing Tidal for sex and pregnancy discrimination.
We reached out to Tidal for comment ... so far, no word back.
