I think the government will interfere with that due to the tax matter. Also I think it would be unfair for the employee if they receive a bitcoin then the price drops because of the volatility of the market also it depends on the country whether the cryptocurrency is legal on a certain country.
I think that should be a choice of that employee.
The fact that the employee are accepting Bitcoin means they know what it is and how volatile it is. Obviously that would raise some brows since that could be really unfair to people that is why companies, if they ever think or thought of paying their people with Bitcoin, they should let them choose whether they will accept Bitcoin or fiat.
Agree, why would even an employee accept something that he doesn't want to use anyway? It will be so unfair especially if he really need the money right away for the bills he has to pay, and we all know almost all of those monthly payments only accept fiat currency. If bitcoin salary is a hassle for their everyday life, then we should not force them to receive bitcoin. We already know that bitcoin today isn't widely accepted in local stores today.
It will be fine as a choice for the employee but not as a fixed rule. Even though I use bitcoin, it's not good to hear as an employee, what more to those who have no idea what bitcoin is, and is living day to day waiting for the end of the month for the salary.
