Estée Lauder fires top executive John Demsey for posting a racist meme on Instagram

Jack Ma recently faced flak for his blog post endorsing the tech industry's overtime culture.

The 54-year-old encouraged employees to embrace the overtime culture if they wished to flourish in the tech world. He was also known to dismiss people expecting a typical, eight-hours-a-day work routine.

Earlier, China's richest man said that people who can stick to a hectic schedule are the ones that have found their passion beyond monetary gains.

Tesla CEO Elon Musk is known for his temper outbursts, and his 'rage firings' have often made headlines. The 47-year-old, whose employees have reported incidents of extreme yelling, allegedly fires any employee who comes his way on a bad-temper day.

Earlier this month, Musk reportedly pushed a former employee who was saying goodbye to colleagues after having resigned from the company.

In another example, it was reported last December that the auto giant's employees were asked not to walk past Musk's desk in case it ruined their career.

Amazon CEO Jeff Bezos is known for his cut-throat management style as much as he is known for being the world's richest man. The top boss doesn't mince his words, and the e-commerce giant has gained a reputation for having a ruthless work culture.

As a leader, the 55-year-old is reported to be a difficult-to-please boss - who is easy to agitate. Stories of his comments including, "I'm sorry, did I take my stupid pills today?" and "Why are you ruining my life?" have often made it out of Amazon's office.

Bezos has reportedly been this way from the start. In 1997, three years after launching the company, in a letter to the shareholders, he had revealed that while interviewing prospective employees he always tells them, “You can work long, hard, or smart, but at Amazon.com you can't choose two out of three.”

In 2017, Uber co-founder Travis Kalanick was forced to exit from the company. The decision was made after he was accused of sexual harassment by an ex-employee, Susan Fowler. But Fowler's account of her time at the company was just a trigger that led to a chain of reactions including complaints of a ‘toxic bro culture’ at Uber.

Soon stories highlighting the unhealthy, sexist work culture that had flourished for years under Kalanick made headlines.

Uber's former Chief People Office Liane Hornsey was forced to leave the company in July last year on grounds of poor management of discrimination complaints filed within the company.

Ironically, Hornsey was Uber's spokesperson on diversity and discrimination. She was also accused of making derogatory comments against the global head of diversity and inclusion.
