With the rules changing for the double vaccinated in the UK, it is likely that businesses that have put foreign travel on hold for a while may soon be able to start again. Although some business trips to certain locations have been allowed, the rules regarding isolation and costs etc has meant that for many businesses it simply wasn’t feasible. As the UK starts to lift some of the lockdown restrictions and the rules regarding isolation if you have received both does of the vaccine is changing, it is likely that the travel industry will slowly start to open up again. Because there is going to be a high demand for flights and accommodation you may expect to see an increase in prices. As many businesses meetings have had to take place over Zoom or other video conferencing software, it could be that some businesses no longer feel the need to travel abroad as much as they used to and are happy with their new way of working.
If you are asked to travel for your business, then be sure that you check up on what is needed to travel and also upon your return. If you do have to isolate you should not be made to take this as holiday, it should instead be classed as working time.
