you only have to look at Boris’s twitter, the pinned post from his speech last night, the amount of people sending in pictures of there work places open and all in a tiny room etc etc, I mean there’s one on there from a builder who’s in his tea room and there’s atleast 50-100 people in there all eatting etc, and this is a building site in London from this morning... so until our wonderful government decide to actually close “non essential businesses” and not just “shops” this epidemic they class it will just keep on going... and a lot more deaths to come.I was joking.
You can't do anything about it. Same thing happened here. They only allow "essential" business to remain open but those who work behind closed doors are also allowed as long as they keep the distance, wear a face mask and gloves, etc.
If you think you company isn't taking any measure and you're exposed to the virus you should be able to inform the police anonymously.
