Tracey Boudine, 50, said she had to use lavatories in fast-food restaurants to escape the ridicule of colleagues at New York PR firm Wise Public Relations.
Ms Boudine, of Brooklyn, in the city, said: “You just somehow don’t feel like a valued human being. You have to spend a lot of mental energy worrying about something that’s a basic biological function.”
She is now suing her former employers for damages.
Court documents filed at Manhattan Supreme Court said Boudine was “teased about her need to use the bathroom, and in particular, her need – as a woman – to use toilet paper more frequently when she did use the restroom”.
And bosses “went so far as to impose a limit on how much toilet paper Ms Boudine could use”, the documents state.
“Male employees were not subjected to toilet-paper quotas”, and she was “relegated to using nearby fast food restaurant and gym bathrooms”.
Ms Boudine – the only woman in the firm’s leadership team during her two-year stint there – claimed she was denied lucrative accounts and had to work “twice as hard” as male colleagues.
She was “subjected to discriminatory treatment and harassment on the basis of her gender”, the court documents added.
Ms Boudine complained to company president, Harrison Wise, but says she was “ignored”.
Her lawyer Alexander Granovsky wrote to the firm in April saying she had been discriminated against “on the basis of her gender”.
But she was sacked “within hours” of the letter being sent.
The amount Ms Boudine is suing for has not been disclosed but includes back pay, lost wages and unspecified damages.
Lawyers for Wise PR, said: “We are confident that once the facts of this case are presented, it will be clear that the claims are baseless, frivolous and frankly absurd.
“We are certain there wasn’t any wrongdoing whatsoever.”
