Workers in Australia could be given the legal right to refuse unreasonable contact from their employers outside of work hours.

The Greens' push for a legislated right to disconnect is gaining support with the Australian federal Government.

The law would give employees legal backup in handling conversations with employers who they feel are asking too much of them.

South Australia Greens Senator Barbara Pocock says they're simply looking at giving workers a chance to say no.

"If you're not paid to be available and it's a big intrusion, not an emergency or essential, you should have the chance to turn off when you clock off."
