I like both Sophia's and WillyNilly's approaches. Of course it depends on the corporate environment and whether there really is someone approachable above Boss's head, or an HR department. You could also try approaching it with Boss in terms of policy/legalities (for lack of a better word)--everyone is living in fear of auditors these days, what if the bank gets audited and they find out the new Assistant Manager was trained by someone who was "clearly" unqualified, because they (you) had not taken the training course and/or were not getting paid a salary that suggested you had the experience to train? Seems silly, but I've seen auditors pick up on exactly that sort of thing, even when everyone involved is being totally above-board. Boss trying to cut corners and save money now could come back to haunt him later.
