Helena Morrissey remembers her worst moment as a woman in the City, London’s financial district. It was almost 20 years ago, when she was the only female on a team with 16 male bond fund traders at Schroders Investment Management. Her young family’s breadwinner, she’d just returned from her first maternity leave and her boss passed her over for a promotion, saying he doubted her job commitment. “I wanted to know if I’d done something wrong or I wasn’t ready,” says Morrissey, sipping water in a conference room overlooking the London Eye.
