A company did an interesting social media experiment on people's acceptance of cryptocurrency as a method of payment for salary.

And I think it is actually a clever way of promoting their token sale, more potential to go viral than other promotional videos I've seen. Anyway, personally I think I would be happy to take cryptocurrency as at least part payment for salary, and depending on circumstances, the whole amount.
I think paychecks using bitcoin seem to be very profitable and I think it does not matter if the employee accepts payments using bitcoin so you should be able to ask the employees or workers you want to pay if they accept payments using bitcoins or not, if they accept then you can use bitcoin as payment.
