That is a tricky topic - I personally was shocked when the poll results have been announced, my colleagues too - my company is HQed in London with offices around the world - not easy for us. I do think England will suffer from it as of various points - as hard as it sounds - even living on the Island England as more in common with us Germans and French folks for example as they would ever accept. The staff problematic is hopefully not a major issue here for EU and UK workers.
What I see problematic for the world is the effect #Brexit had on other movements in Europe (France, Germany, NL etc) where right wing parties grow and grow - the US election proved a new "protecting our frontier and focus on our country only" mentality which is dangerous - not only for the EU or England - no dangerous for mankind.
We will see why happens next.
Yes hopefully the workers issues get resolved quickly. I hope this was not for reasons of nationalism and bigotry but we will have to see.
