I believe in bitcoin but until it gets to be stable. It just isn not useful to get paid in it. I would probably take some of my paycheck in bitcoin just like some of my current paycheck goes into my retirement plan but definitely not all of it.
But that's the fun of having your salary in bitcoin. The chances of it to fluctuate is nearly the same as the chances of it going up in value.
Although if I had a job that's really high paying, I too wouldn't want to risk it by receiving my salary as bitcoin.
I heard the news that oversotck.com allow the employee to have part of their salary in bitcoins. But I do not hear furhter news about that.
