Working under a male senior

Q: I am a single female and have been studying something in the business field not really realising the extent of this. I started working at a company
recently and there is a male senior who I have to approach when I do not know what to do. 

  1. Should I be leaving this job?
  2. If don't end up working after the studying will it be a waste I commited?

Wazifa for labour problems

Q: Is there any dua I can pray in the shop for a worker that is troubling, comes drunk to work, if he don't want to come to work he doesn't come. I need something to pray so either he comes right or he leaves the job. I can't fire him, he has to leave on his own. Jazakallah

Income earned through leasing one's property to the bank

Q: Can you explain to me the reason why Ulamaa so severely condemn the earnings of banks? In today’s times, the majority of the wealth in banks is acquired through the deposits of people which are from halaal. Hence, if one leases out his property to a bank, the income should be halaal based on the principle that if 50% or more of one’s income is halaal and such a person has to give you a gift, you can accept it.
