Knowing the following is pedantic, "Wherever you go there you will be". Purported morale issues aside you can't make people feel good about themselves, but you can be teflon and work with the options you have and not worry about the ones you don't. Are you mature enough to not be entangled in the snare of faint and negative environments and still get your job done to the best of your ability? Or, do you need an outside structure to allow your success?
