What does a government employee do if his job conflicts with his private contracts?

Question:
He says: I am an employee in one of the government departments, and we are bound by contracts with private entities. Sometimes, instructions come to me from our superiors that contradict what is stated in the contract. What is the ruling on obeying the superiors in this work?

Answer:
It is obligatory to obey the superiors in this work because you are an employee and you receive a salary for your work. It is not permissible for you to be bound by another job that interferes with your official duties. The system prohibits this. Either you devote yourself to the job, or you leave the job and go with the work you want. As for combining this and that, it is not suitable; it interferes with the work and violates the system.
