Personally I won't. Because many facilities in my area doesn't support BTC payment. I do not mind receiving, say, 20% of my pay in BTC denomination.
For me also, I would not receive my salary in BTC because it would be useless to receive in BTC and then convert it to BTC later because I wanted to buy something and then I can't buy it with BTC because they only accept fiat. Maybe one day when almost all the stores will accept BTC as payment then I can also accept my salary as bitcoin but now it would be hard because many people don't even know that a digital currency exist.
If you are investing in bitcoin, it is good to accept bitcoin as salary. You do not have to buy bitcoin anymore in order to invest. But if you are using bitcoin just for daily expenses, it is an annoyance to exchange it to fiat.
Even if we accept salary in bitcoins then also at this stage we need to exchange it to fiat for our daily expenses so I don't think it would be smart to accept salary in bitcoins.
