we could make more money if paid in Bitcoin.
How is that possible? You mean equivalently in fiat you get more bitcoin because you don't need living expenses for 2 weeks, not because you chose bitcoin?
Probably what @AVE5 meant is that when we get paid in bitcoin, the price of bitcoin goes up in value the next day so technically you're making more money but the opposite can be true too, you can get paid less all of a sudden when the price goes down.
