Permissible and Impermissible employment

Q: I work as a customs officer who collects tax from people. I had heard that it's haraam and I really want to know the truth.

Q: In a banking institution the only income they do earn is through Riba. There is no other income generation process involved in a Bank's system. And it means, a bank is paying salaries and profits to all of its employees and partners through the generated income which is nothing but Riba. In that scenario, how can it be legal for an employee to receive such an income which he knows that is paid to him through Riba, and at the same time he knows that he is a part of the machinery where business is nothing but to generate Riba income. In my opinion it becomes totally invalid for a muslim to be associated with a banking institution. Am I right?

Q: My son applied for a job as a facility manager in a habiba bank London where we live. He had an interview and now he has been offered a job. He did ask them about income. They said its not related to any finance department. His job will be working under someone else as a facility supervisor, building and outside jobs. He told me that he will not be working directly in finance. My concern is should he accept the job?

Q: I want to ask that earning from a intercede (shifarish shuda) job is halaal or haram? I mean my friend was not fully qualified for a job actually government is equipping clerks in schools. The criteria is a typist who can type 80 words per minute and they prefer to inter pass. While my friend can type but not according to demand and his typing speed is very slow and he is matric pass and doing his inter. He submitted a typing certificate in which it is written he can type 92 words per minute while his typing speed is very slow. So he applies for that job and a famous man intercedes on his behalf and he gets selected so earning from that job will be halaal or haram?

Q: Alhamdulillah, I have been offered employment. However, I am concerned as according to the contract and information from the human resources department, it is compulsory for me to belong to the company's current provident fund. This fund also includes a contribution towards life and disability cover. My questions are as follows: 1. Is it permissible for me to accept the employment contract? 2. If I may accept the contract, what would I do if the fund either pays me or my dependents? May I give the returns (interest, insurance benefits) to the poor and keep the capital investment (my contribution and the employer's contribution) for myself?
