For Shari Storm, senior vice president at Verity Credit Union, periodically applying and interviewing for other jobs has helped reinforce that she is exactly where she belongs.

"A mentor I always admired told me a long time ago to interview for other jobs every six months," said Storm, who is also the author of Motherhood is the New MBA. 

"Not only as a way to practice interviewing because when you go for that big job you really want, it shouldn't be the first interview you've done in 10 years, but you're also always able to articulate your market value. The most important reason though is if you do get an offer, by deciding to turn it down you recommit yourself to your current job. Sometimes people stay in a job just because they are either too lazy, scared or nervous to try to do something else. I think it's really pertinent in the credit union industry where sometimes people stay for decades. If it's passion keeping them there great but if they are staying because they don't want to step outside their comfort zone it's not fair to them, the credit union or the industry as a whole."
