That’s the caseMy understanding was,and still is,if you came back off holiday from one of the listed destinations,you 'just' self isolated for 14 days and a test wasn't necessary.
Of course if you displayed symptoms or started to feel unwell you could ask to be tested? Irrespective of the outcome you were still deemed to be in self isolation.
Some employers seem to be making rules up as they go along to suit the needs of their business and some employees have done similar to suit the needs of their wallets(I'm not in any way being judgemental of the 2nd scenario) because numerous families live hand to mouth.
