Nothing good can come of giving your supervisor negative feedback. Use the situation as a learning experience, and while you're learning to manage upwards in order to preserve in-office sanity, try these three simple steps. 1) Start planning an exit strategy by networking within your industry. 2) Tell your boss that sometimes you aren't able to respond to his/her needs as quickly as you would like: could the two of you find some time to sit down and discuss better communication strategies. 3) Immediately contact your human resources department; be honest, upfront, and ask for their advice/help. Do not, however give the impression that you're about to jump ship, but rather that you're trying to make it work.
Keep in mind, your 'bad boss' will discuss your performance with fellow employees at some point, and you want those comments to be positive.
