At the minute I think if you travel for a holiday abroad then you have to suck it up if you are quarantined, rather than ranting, because it is a known risk at the minute. If you decide to go in spite of the obvious worldwide situation, then you deal with the possible consequences. That said I hope the travel industry keeps going because it props up a lot of the economy. People who travel just need to be prepared to do their bit. If it means missing work due to unexpected quarantine then that’s a price you should pay. Or, just don’t travel.
