I would agree that it is temporary but I think 3 months is optimistic.
Whilst the virus might be past it's peak in 3 months, there will be a lot of people who will have been on reduced pay during that period and will not be in a position to take holidays. Others are being encouraged to use up their leave now so may not have much to take come summer. You must also remember that different countries are at different phases of the epidemic so global industries won't get back to normal until the virus has been around the globe.
I would imagine that it will take at least until this time next year to get to anything like normal and the new "normal" won't be back at 2019 levels even then.
I have a friend who works for Manchester and understand staff are on 90% pay for the whole of the financial year that is coming up right round until April 2021. I don't think anybody really knows for sure but it sounds like they are thinking along similar lines and playing the longer game.
