When you land a new role, you want to tell everyone what it is and where. After all, it is exciting! It could be your dream job and, these days, if you are on a job search, you might have been looking for quite a while.

Although you will give proper notice at your current job, however, you probably should keep the details about your new job opportunity limited to to yourself and your family until your first day.

Why?

Especially before all of the tiny details are arranged, you don’t really have a deal. If you have received an offer but the paperwork is still processing, you have not truly landed. Let your colleagues know you are leaving, but keep the specifics to yourself for the moment.

Even after all of the logistics have been worked out, you are still not in the chair and your name isn’t yet on the office door. While you are in limbo, resist the urge to make an announcement. Your new company might want to do it first and you don’t know their policy. Better safe than sorry.

Be extra careful about talking on social media about your new job. Careers have been made or broken right here. In one story we wrote about last year, a candidate’s offer was rescinded because they started posting about it too soon. Don’t list your new role on LinkedIn until you have started onboarding.

On your first day of work, you can make your excitement about your future public knowledge. Be thoughtful about thanking your colleagues for their support and write professionally about your new position. It’s easy to gush, but everyone is going to see your news–including your new manager.

And enjoy it! It’s not every day you get to start something entirely new!
