As usual, the Government is being deceitful in its campaign. The aspects of the cahnges they are focusing on as being protected by law, like being protected from dismissal because of family commitments, and having a union represent you at work, are ALREADY protected by law. It's the stuff they're not talking about, like the changes to working hours, penalty rates, leave loading and stuff, that people are concerned about. But of course, they're just going, well, you can't be sacked for taking a day off to look after the kids, so everything will be okay.
Mind you, some the union ads are a bit over the top as well. There needs to be changes so that bad workers can be given the boot. There are aspects of the current laws that force employers to hang on to useless, lazy and sometimes dangerous staff because there's virtually no way to sack them, and they need to be addressed. However, I can't see how some of the changes that are being proposed are going to help anyone other than employers. It's not worker-friendly legislation. Workers will be screwed, as usual.
