Cryptocurrency is an innovation, so if someone is willing to pay a salary or receive a salary with crypto, then that person has fully supported the adoption of this innovation. I was once an employee and to be honest, if I were still an employee, I would be willing to receive a salary in crypto currency, but I prefer bitcoin because the price of bitcoin fluctuates so the profits received can be greater than just receiving stable coins.
Depends on the nature of job, if it's a more physical job like teachers, doctors and a few professions then their is no need paying them in Cryptocurrencies, to save them the stress and put them in a more convenient state to make good use of their income with our consistently bothering on how to sell them. But, if it were to be those who mainly work online jobs then it should be an agreement between both parties, as long it is convenient for both of them then their is no worries it is also a good means of payment.
It doesn't matter the nature of the job. What matters is if the company supports payment in Bitcoin then the client is allowed to choose the method of payment they want. All jobs are jobs whether online or not the agreement has to come from the company and the worker. If agree then it should be done that way.
