UK relocating to Greece after brexit 2021

Hi I'm from the UK and I have been offered a relocation package working with Teleperformance to Greece I want to know if anyone can help or give me some information about going to Greece for work after brexit

Sounds like a great idea, thanks to Nigel ...now if you want to come and reside in Greece ..You can....
For a 90 days stay without visa in any 180 days period....For a longer period you will have to contact the Greek embassy .

I don't think that UK is the same as other countries not members of European Union. As you are relocating for work invited by a company you will have no issues with your papers and you will not be taxed for bringing your belongings. Have you inquired with the company on such issues?
