After you get settled into the job, I would suggest asking if you can bring your bike into your office (or cubicle). Granted, I don't work at a bank, but I work for the state in a large office tower at Five Points, and there has been no problem with me bringing my bike up to the 15 floor and parking it in my cubicle. It never hurts to ask--all they can say is no. If you get nowhere with finding a safe place to leave your bike and you work for a large corporation, find the person in charge of promoting physically activity (to lower insurance costs and absenteeism). Perhaps they can help you find a good place; someone who exercises regularly can be an asset to the company (and makes a good story in the company newsletter).
Good luck and let us know how it goes!
