Of course, it will all depend on the country you were placed in, if you are in the countries who against the use of any cryptocurrencies especially Bitcoin then this is definitely foul on the government, and if not then it is up to the employer and his/her worker come up to. However, I don't think it is a good idea for us to use Bitcoin as a wage simply because crypto is too volatile this might only cause confusion on the common people who don't have any idea on it. Moreover, crypto commonly works as an asset for an investment comparable to gold. Therefore, think we should leave fiat on this matter.
