“It’s not my job.”

Taking responsibility inevitably sets you up, while watching from the sidelines gives you that head start should an anvil hit. There’s always the option to run.
When you step in to do a little more and claim ownership (no matter how small), the work becomes personal. This is where thoughtful decisions are made and jobs are performed with integrity.
“It’s not my job” is too big of a shortcut to take, especially if you’re hoping to get someplace else. Whether you’re looking for a raise, a promotion, a better position or a more flexible company, venture beyond the lines of your job description and look for ways to help your team succeed.
It might not be your job, but it’s definitely your reputation. How safe do you want to play?
