Why don't changes in pressure affect change in work?

Pressure does affect work, at least for gases (think our two equations for work that contain pressure). I think in terms of solids and liquids, pressure wouldn't affect because it's extremely hard to compress liquids and solids. Hopefully this answered your question!

w=-p*deltaV, so pressure does in fact affect work.

Work does affect pressure. W=-PdV
