Spearheaded by Lifeline Australia, the day is on Tuesday July 24.

And, it is meant to be fun.

Lifeline's mantra is to help reduce workplace stress in 2018 by registering a record number of workplaces or community groups willing to participate and implement simple activities that can help reduce stress.

Research shows that 90 per cent of Australians need to stress less - with a massive 74 per cent reporting being stressed from work.

While the initiative is designed to reduce stress, it is also aimed at raising vital funds for Lifeline Australia.

Lifeline's chief executive officer Bob Gilkes says the day is a fun take on a serious issue.

“Stress Down Day provides a great opportunity to realise the importance of ensuring an environment that prioritises the well-being of employees as well as members of the community," he said.

"It’s a fun take on a serious issue with the bonus of doing something good for our community.

“Stress Down Day is designed to be flexible, so activities can be tailored to suit the workplace culture. 

"In previous years, some organisations have encouraged employees to wear pyjamas or tracksuits to work, others have gone Hawaiian.  

"I’m looking forward to Stressing Down by wearing my Ugg boots to work this year,” he said.

Mr Gilkes suggests Australians should use the opportunity to have fun, promote happiness and encourage help seeking. 

Workplaces across Australia are encouraged to get involved.
