What makes it any safer today than it was a month ago, when we were seeing exponential growth all over the country?
Most workplaces do not allow social distancing. Many minimum wage employees take transit to work, which does not allow social distancing. Many of them would be completely ruined by medical bills if they catch COVID-19 - even if they don't need to be hospitalized. A single doctor's visit can run you hundreds of dollars in this country. Many of them live with vulnerable people, who would die, if they catch it. Many of them are currently taking care of children.
Are you ready to pay for their medical bills? Their transportation? For rebuilding their workplaces in a manner that allows social distancing? Are you going to watch their child while they are at work?
If not, don't be in such a hurry to send them back to work.
