Show test before working again?

Among social media groups, reports that businesses have been asked to require their employees to undergo COVID-19 tests before being allowed to work again have become the subject of many discussions. One netizen asked the rationale behind such proposed move. “If being negative is a requirement,” he said, “how sure are these companies that those negative employees will continue to be negative as they report for work?” The possibilities of contracting the virus is endless. Thus, he added, workers should not be required to go through those tests.
