This is a very good question. The answer is that the UK will “Brexit fully” on 31 December, 2020. On that date, the current transition period (in which we are no longer a member of the EU, but are still subject to all EU laws) will end. This means that business immigration and Tier 2 (skilled worker) visas will be THE big employment law issue of 2021 in the UK. Today, a Parisian banker wanting to work in the City of London can just come and work (no work permit is required). From 1 January, 2021, this will all change. This will result in a massive increase in costs and administration for businesses wanting to recruit skilled EU nationals to the UK.
