You know what they say: You can't help others until you've helped yourself.
Unless you're that (hopefully rare) person who pursued aid work as your career just because it sounded good or just because the salary's not so bad, you probably committed yourself to aid work for a reason. You want to help others.
Well, unless you're prepared to defend your own well-being & call on your employer to prioritize the well-being of yourself & your colleagues, you are unlikely to enjoy the personal time you deserve, appropriate care following traumatic incidents, necessary reprieves from deep field placements, etc.
It's important to recognize your responsibility in leading a healthy lifestyle in order to truly make a difference in the lives of those most in need.
motivate action from survivors to unite to defend ourselves and in so doing help render staff healthier and thus more effective in their role
