"Going forward, to build a breakthrough Twitter 2.0 and succeed in an increasingly competitive world, we will need to be extremely hardcore," Musk wrote in the all-staff email. "This will mean working long hours at high intensity. Only exceptional performance will constitute a passing grade."
It's the attitude of a rich and entitled loser who thinks they know what "hard work" means without ever engaging in it themselves. These morons use language like this to, in their mind, weed out the weak and lazy, but in reality it just sounds deranged and is a massive red flag to any employee with a functioning brain.
Many companies promote a work culture where heroic employees are supposed do long hours for free just because good employees are passionate about their job. That's just exploitation.
