Does that include required masks?
Are temperatures taken at the door?
Are “at risk” recommend to stay home?
Like Harriet said: No masks.
I think what you read, Harriet, is an article about can an employer force an employee to take a temperature check. I haven't fullly read it, and it was a while ago, but I believe an employer can't because it's medical information. And only medical personnel should take temperature checks, but don't shoot the messenger if it's wrong
The update we received in the Netherlands yesterday for our exit strategy is partially the same as before: Work from home as much as you can, no unnecessary travel or outings. If you can't stay 6ft away from each other, go somewhere else. Masks are only required when we cannot keep our distance. They have done tests in the public transport, but it's not possible, especially not when in the coming weeks more people will start travelling again because more businesses restart.
Risk groups are just asked to pay better attention and those who aren't in risk groups are asked to keep the risk groups in mind.
Those who have (cold) symptoms stay at home, If these symptoms include fever and shortness of breath, the entire family should stay home.
So only healthy people are allowed to work, and move around, and then masks shouldn't be necessary. Our government hopes and trusts us that people will use this 'freedom' wisely.
Places that can re-open per next Monday (hairdressers, beauticians, close contact professions) or per June 1st (restaurant, museums, etc): But only with appointments/reservations, no walk-ins, they have to scale back capacity to create space between their customers. When you enter, they have the right to ask you questions about your health (again hopefully everyone will be honest), and take your contact details. That IF something happens, they can use these details for investigation.
Back to the theater, the theater season is almost over, most theaters are closed in July/August. Many shows are already cancelled, but many theaters or production companies have already said that they will cancel more shows because 30 people including staff is almost impossible for many. They will probably watch movie theaters to see how they are doing, and wait till the audience can be scaled back up to 100 people. Or wait till September and see what the options are for the new season.
