I'm finding it hard to pick it up as I go along, but there is a culture here of not admitting to weaknesses or ignorance, so I'm terrified to tell anyone that what I really need is a crash course in banking. I can't carry on as I am. Do you have any suggestions?
A Come clean immediately. In a few months' time it will be too late. Whatever the culture, you're still a newcomer. You won't be fired now for wanting to become more effective at your job. But you might be, this time next year, for making a crucial mistake as a result of basic banking ignorance.
