Can Twitter’s new female CEO actually change the sexist culture or is it just some kind of box-ticking exercise?

The San Francisco-based social media platform altered its previous policy to “whatever is required by law in the region where the employees work, along with a ‘top up’ of two weeks of leave,” wrote New York Times reporter Kate Conger, who cited the internal memo.

There is no national policy for paid family leave in the US. However, the Family and Medical Leave Act gives certain employees “unpaid, job-protected leave for specified family and medical reasons” for a period of up to 12 weeks.

Musk’s change in policy puts Twitter workers seeking additional paid leave at the mercy of the state in which they live.

Then, of course, there’s the on-going sex discrimination cases being filed against Twitter after Elon sacked thousands of staff. In December, two former female staff members filed an unfair dismissal claim against the tech company, arguing that more women were laid off than men. They claim that 57 per cent of female staff were laid off during Twitter’s mass sackings on November 4, compared to 47 per cent of men.

In a court filing, the former staff claimed Musk had unfairly demanded staff commit to “extremely hardcore” working hours, despite knowing this would force mothers and female caregivers to quit.

The former Twitter workers stated that some staff were told they would need to work “24/7” to meet Mr Musk’s product demands and sleep in the office.

Yaccarino herself is a mother of two who has built her career as an advertising executive, starting out in media sales before working her way up to becoming an executive vice president and chief operating officer, before joining NBCUniversal – one of the world’s leading media and entertainment companies – as chairman for global advertising and partnerships.

She was described as “a marketer’s leader” by Mark DiMassimo, founder and creative chief of ad agency DiGo, who added: “She understands what marketers need.” However, will she have enough power to make a U-turn on some of these awful policies that do nothing to support women and parents in the workplace and overhaul Twitter’s image and – more importantly, Elon Musk’s?
