Welcome, JanaA.
I'm not sure if there is any such thing as what a framing manager normally makes. Another question might be, "What really defines a framing manager?" The real answer is, "It depends."
It depends on the area you're in and its cost of living and rate of growth, plus the demand for good framing and the level of supply associated with that demand. It depends on your workplace: whether it's a prosperous, well-established business with a loyal clientele and whether you've established yourself as a real key to its continued prosperity. It depends on your relationship with the owner and the owner's alternatives to your services.
The desire to imoprove employees' wellbeing is always balanced against the hard realities of the present economy, however it happens to be. I urge you to open a dialogue with the owner for the purpose of discussing a raise. Be prepared to demonstrate your value to the business with recent examples and strive for an open, honest dialogue which, however it turns out, leaves both of you with a feeling that the thing you just did was a good thing, instead of leaving one or both with a sour taste. No matter the outcome, your relationship and understanding will no doubt be strengthened which will lead to other growth.
