Yeah, with the price of everything, it would be really bad for almost anyone to lose their job with zero notice. But to lose an entire months worth of income would be disastrous for a lot of people. There's only so much savings and family can help.
My first thought for a good safety net for cases such as these is perhaps the government should introduce some sort of wage guarantee, like what exists for personal bank accounts. An extra 0.5% business tax could be collected from businesses over a certain size, and in the event of any insolvency where they're unable to pay their staff, that fund is used to pay them a couple of months salary.
Or maybe something similar to super but for emergencies could be created and mandated. Or maybe the gov should stop acting like a few Centrelink payments will bankrupt them and hire some fucking staff so claims don't take 4 months to process
