It is hard to change a culture if you are not in a position to do so. My recommendation, stay focused on your personal end game. Where do you want to be in 15-20 years… back track to where you are now and figure out what steps you will need to take. You have a job in design and that is a great start. Put some weekends into some portfolio building concept projects. If you were in charge of you company what would you design? If you were in you dream job what would you design? Channel the negative situation into positive action. Get that folio together, post it on coroflot, behance, et all and make the next step on your path.
The alternative is acceptance of bitterness.
