5. Prep for a job hunt
Unless the need to disembark is dire (say, harassment coupled with an unsupportive HR department), spend some time getting your ducks in a row before you jump ship: Update your resume, website (if you have one), and LinkedIn (with the share buttons turned off so your changes aren't broadcast to your network); Google yourself and make sure nothing untoward comes up that needs attention; and ping your references to let them know you’ll be leaning on them.
