My daughter-in-law works in a property management company, and now she has a very big problem. I don't know if I should let her continue working.

This matter is divided into two parts:

1. If the elevator fails to pass the security inspection, the property management company shall require the elevator maintenance unit to issue a letter to prove the reason why the elevator needs to be stopped. As for the contact information of the maintenance unit, this is not what your daughter-in-law needs to worry about. She only needs to report to the leader and explain to the owner who has been asking.

Since the manager doesn't come forward, there is still a property management company. Property managers or property management companies need to sign some responsibility letters, but your daughter-in-law can't. What she needs is to report to the leader. If the leader can't contact, contact the superior leader.

It is recommended to do a good job in writing and do your duty.
