Have a look a the Fair Work site about terminations and redundancies, just to educate yourself.

It does make good business sense that the owners do learn about the business, sometimes that can be good for everyone as they sometimes implement some much needed changes. Other times, of course, it can not be great for the staff.

Hope it is all fine for you and that if they do decide to move you on, that they at least give you a payout. Best of luck.
