Without email, people in the age of the Internet can do. And try to close kindergartens - and a lot of mothers and fathers of different professions will not be able to get out to work!
I authoritatively confirm. We once moved the working day to Saturday, and not to kindergarten, and a couple of child workers had to bring the baby to the office. There were only a dozen on our whole floor, but in a couple of hours we could see a wonderful picture... The director in the middle of the corridor ripped his hair and spoke: “Who let them in at all?” What is a working day? Worked already! Drop the naphyg with your codename from here, and in five minutes no child in the building!
