Our company recruits new employees, and one employee is found to have suspected occupational disease (pneumoconiosis) through pre-job physical examination. How to write an agreement?

If the job you arrange for this person may be exposed to dust or other occupational hazards that affect the respiratory tract, then you must not continue to hire this person! The law on the prevention and control of occupational diseases has clear provisions! The so-called exemption agreement you signed has no legal effect at all, because your behavior is illegal, so such an agreement is invalid! Once there is a dispute, your so-called agreement will be like waste paper!

Doesn't anyone in your company have some basic legal knowledge?
