According to the Law on the Prevention and Control of Occupational Diseases and other relevant national laws and regulations, the employing unit shall regularly arrange for workers to undergo occupational health examination during their on-the-job period according to the occupational hazards exposed to them. No matter whether the employee is voluntary or not, the occupational health examination during the on-the-job period cannot be cancelled.
Because once employees are diagnosed with occupational diseases in the future, enterprises need to show relevant certificates such as occupational disease physical examination reports. If the enterprise cannot provide strong evidence to prove that the employee's occupational disease has nothing to do with the enterprise, the enterprise still needs to bear relevant legal responsibilities.
