Be all in for teamwork but make sure you have a record of your own work, so that later, when a coworker shows any intention of stealing your work, you have a say in what you have worked upon. Next, go public with your ideas. If you want to wait for feedback on an idea, that is fine, but start telling out loud your ideas because you never know when your coworkers slyly steal your ideas and voice them as their own.
