Without mutual trust you can't do that I have work in an establishment where I was appointed to manage the fund and finance of the firm but really serious after short period of time I was told to quite that position to avoid problems,since some time the finance of that firm will be tempt but when I complained to the management they cant take appropriate action,thus living all the fault on me so I have to vacate that position
I would never be comfortable walking in any position in a company that is always going to leave me compromised in a way I will have to be the one of these going to suffer for something I shouldn't be the one taking responsibility for.
It's why when it comes to finances right now, I try as much as possible to stay away from it because there is always complications in keeping the financial record and cash intact.
