I work for one of the maintenance companies on a monthly salary, and sometimes the homeowners give me an additional amount

Question:
He says: Honorable Shaykh, may Allah grant you success. I work for one of the maintenance companies on a fixed monthly salary. I work for one of the maintenance companies on a fixed monthly salary, but when I go to homes to repair some appliances, some of the owners insist on giving me an additional amount. I refuse to take it, but they insist. Is it permissible for me to take it?

Answer:
No, it is not permissible for you to take it while you are an employee hired to perform this work. This is a bribe, because if you accept it, you will be diligent in the work for that person, and if you go to the second person who does not give you anything, you will be negligent in the work and look forward to the payment. This ruins employees and workers. Bribery is the ruin of society. Is this work not permissible? Yes.
