I don’t think this is true. I’m in the building industry and construction sites haven’t been ordered to close, so they aren’t being advised on when to open.No idea on the detail but government are telling specific sectors messages to get ready, construction as of last week have been told to get mobilised and back on site next week (and they are). Football have been told restrictions to start be lifted from the 1st June, so therefore football to restart 6th June behind closed doors.
All very hush hush, with no overall picture
Any construction sites that have closed have made their own decision either because they couldn’t run safety or it isn’t economical to run with a reduced staff. The single biggest reason though is a lack of supplies, manufacturing has basically stopped and you can’t get orders for plasterboard for love nor money.
