"Strike to save the planet" - Atlassian co-chief executive Mike Cannon-Brookes urges staff to be activists in climate crisis fight

Global tech company Atlassian will support its staff with special paid leave to participate in the so-called "climate strike" later this month. 

Atlassian's outspoken co-chief executive Mike Cannon-Brookes says climate change is now an "existential threat", backing climate activism as the new corporate social responsibility and critical to the survival of capitalism. 

While joining the strike is voluntary, Atlassian staff will be able to use all or part of a week's special volunteering leave to protest the lack of action by world leaders.

Mike Cannon-Brookes singled out Australia's prime minister Scott Morrison when he spoke in Sydney with ABC's Peter Ryan.
