Tension with your employer or client makes you nervous. You're tired of bending over backwards to satisfy their unreasonable demands. Resist the temptation to break off this relationship. If you work for a company, don't quit until you find another position. It's always easier to find a job when you have one. Are you self-employed? Complete an assignment as promised. At that point, you can end the alliance. Abandoning work will harm your professional reputation. Protect your interests.
