That is true in how workers should be. I am not from Australia, but a lot of workers might feel pressure to answer for fear of some kind of actions (likely a higher chance of being written up for some other BS). While this pressure could still be felt and managers can always find reasons to go after anyone. I think that given the way that fucked up work practices have gotten worse (at least in my opinion), it is very important that shit like this be added to laws.

Any pro-worker protections that can help fill the gaps where unions are missing/lacking is good while capitalism is the way of the world. And of course should be some of the first laws and constitutional setups in all anti-capitalist states as personal times should be important and separate from work times. So in all states/nations there should be clear rights for workers and place lives before profits/jobs.
