Re: Silver Lining
The reverse is obviously also true. People with only UK Citizenship (about 60 million Brits lost their EU Citizenship in January) will no longer be automatically allowed to work in the EU.
A friend of mine is an ex CapGemini director who was giving those eye-watering costly trainings (you know the ones, those that make you think fondly of how cheap a whole year at university was) to people all across Europe. He will now have to apply for a work permit for a day's training in Milan or Berlin and so had to radically change his whole business model.
It's also been causing some issues in sectors where products or services come with maintenance contracts. You can't easily send Dave from the Warrington branch to the client in Ludwigshafen any more for annual maintenance or on-call troubleshooting. You'd either need to apply for a work permit for Dave or need to find someone with an EU passport for that.
I attended quite an interesting presentation on the impact of Brexit on HR policies two years ago. Not only did it state that Irish Citizens have now been promoted to god-status as they have the automatic right to work in the EU and the UK (because of bilateral UK-IE agreements), it also highlighted that in the UK we could see the phenomenon that people who kept their EU Citizenship in January and have Settled Status in the UK will become sought-after in some sectors as they can still work anywhere across the UK and the Continent without requiring a work permit.
