"Test, test, test" was the motto of the World Health Organization at the beginning of the corona pandemic.

According to the revised Corona Occupational Safety and Health Ordinance, employers must now offer their employees test options.

However, employees are then not obliged to be tested. "The Federal Government recommends" only to make use of the offer, it says on the website of the Federal Ministry of Labor and Social Affairs (BMAS). However, a test requirement can result from other requirements. However, they are difficult to understand without legal knowledge. This leads to problems in practice.
