The key is to be mindful: "You need to be sure you are communicating what you want your management to know," says Clinical Professor of Management John Millikin, Ph.D. of the W.P. Carey School of Business.

1. Things You Wouldn't Share with Your Direct Manager
HR is there to help you deal with your manager, but they're also there to help your manager deal with you, so don't count on privacy.
"HR works in that difficult space between employees and management, and must act on serious issues they learn about, whether you want them to act or not.

Your HR staff is tasked with keeping your work life well and functioning -- your home life isn't usually their business.
This includes "medical conditions, whether it be personal or family ongoing or past physical or mental issues...or financial issues like foreclosure," notes Lauren MacArthur, CPC and Partner, at Winter, Wyman & Co. a Northeast staffing firm.
The reason? HR wants stable performers and may be concerned if aspects of your home life seem unstable. Of course, if you need their help in order to do your job because of these issues, then you may need to discuss them, but do so cautiously.

At some point during hiring or after, your HR rep may check out your online profile just to make sure you're not bashing the company online or acting in a way that reflects them poorly.
So it goes without saying to never post inappropriate or potentially offensive photos, videos, wall posts, updates, or other content on Facebook or other social networks.
Next: How much you loved your time off
If your company gave you maternity or paternity leave, mention how much you appreciated it to HR -- but show them that you've integrated back in and are glad to be back. The same goes when discussing a past leave in a job interview.
"You don't want to dwell on why you took any leave (parental or otherwise) because it's not relevant, and you want to move on to what's relevant" -- like your current skills and experience, says Caroline Ceniza-Levine, Partner, Six-Figure Start and co-author of How the Fierce Handle Fear; Secrets to Succeeding in Challenging Times.
