The best thing you can do if you want a flexible schedule is ask for it. Younger workers are finding more and more success when they ask, which should give everyone encouragement to request flextime if they want it.

Laurie Young is a founder of Flexible Resources, a company that specializes in finding flextime jobs for people, and she spends her days convincing employers to create innovative positions. You will probably have to do some convincing as well.

It makes sense: You’d never ask for a raise without presenting competitive salary analysis, and you should do the same when asking for flextime. Fortunately, there is a lot of research to present because many companies offer flextime, and it actually helps those companies because flextime is a cheap and effective tool to boost employee morale.

But keep in mind that flexible schedules aren’t available to people who get the job done. Flextime is generally only offered to overperformers. So be one.
