There is "art" and there is "design". It feels like OP might be confusing the two. The latter is about creative expression within the confines of constraints like time, money, function, etc. The former is not. Doing graphic design work at a commercial enterprise is a creative endeavour constrained by commercial realities. Perhaps the OP just needs to accept that he is working in the real world. They should probably find a creative outlet that is creating art in addition to their design day job.
