If you have to ask you probably want to be paid in fiat and put your surplus into bitcoin. Otherwise you might have to worry about tax implications of spending bitcoin for daily expenses etc.
IF they are guaranteeing a certain amount of bitcoin
IF you think the future value will be worth the work
For an easy example, let say bitcoin is currently $50k. If your salary is $50k, and they agree to pay you 1 bitcoin (not $50k worth of bitcoin) for 10 years, I would take that deal because you are possibly getting $100k+/year in the future.
If the deal is "We'll pay you $50k worth of bitcoin", I don't really see the point.
i guess that depends
are you paying tax over the wage in btc?
where you buying your bitcoin?
If you are using an exchange you are loosing fees along the way. Direct onchain transaction to your wallet will save you fees i guess
