One way for the poor to improve their living standards is to move from bad jobs to better ones. That can involve switching within sectors, between them, or from one place to another. This mobility is not an option for everyone and many barriers exist: nor is it necessarily the case that leaving one job for another will automatically bring extra earnings. But there is more mobility in informal employment than might be expected and overall in many cases mobility for the poor does increase their earnings. Integrated policy frameworks spanning employment, social policies and migration are needed in order to ease the transition to better jobs.
