Andrew McGregor, a young professional in Sydney, was sick of a culture that thinks staying late in the office is OK, so he posted his thoughts on social media.

The post went viral! It's been read by more than two million people and commented on and shared 50,000 times over.

A lot of those comments were pretty brutal - "Andrew, you're deluded and will never be successful."
