What's surprising here? I don't think so - and of course your boss has the option of paying you in bitcoin as long as you both agree to the payment. Regardless of where you live, I still don't know if your country has legalized bitcoin as a means of payment, but if it is illegal then surely paying salary in bitcoin shouldn't need to be made public.
The salary payment in CBDC will not differ from the salary in fiat, as it is just another form of money. In fact, when you receive a salary in CBDC, you can also convert it to bitcoin if you wish, just like now you can convert your fiat to BTC.
Exactly, CBDC is fiat in another form. High volatility can be minimized with CBDC, so that governments can adopt it to pay salaries instead of adopting bitcoin. I'm more likely to receive CBDC as a salary although some of it I can convert to bitcoin or altcoin.
