That's right, on remote works, most of the time we get money only for the hours we work for. Now, if because of illness or holiday, if you don't work, you will not get paid, which will affect you financially, people say you can work when travelling, but not true. After exploring a few hours, you will get tired and once you back to the hotel, you will want to sleep or take rest, if you still work it will not be productive neither you will enjoy the holiday. So, besides remote jobs, it's better to invest in something that will earn money without your involvment.
