I won't accept it as a form of salary because it is really unstable at this time......

Well we are not the same wanted so i think for me i want to accept bitcoin as my salary but they should relay in the present price before they send my salary.. so that i have time to hold and sell it in the right time..
but until now i am not satisfied in earning in bitcoin..
yeah if the company continues to use the rate bitcoin is up to date to make salary payments to you I think you'll still get the amount of salary the same, but you should know that in order to convert it again into fiat, you will apply a fee to launch an exchange or put it into a bank , so you should consider it as well
I don't think that company will prefer to pay you salary in terms of the price of bitcoin, once your salary is fixed in bitcoin companies will pay you the same amount of bitcoins irrespective of the price.
