Would you go into a basketball game and yell, "I got this! Stay out! I can do it myself!"
Your co-worker's eyes and ears and experience are like silver in a mine. Use them. A group is always stronger than an individual. We are all learning and growing. Policies, protocols and equipment change constantly. Don't be afraid to say, "Will you take a look at this Arctic Sun and see if I've got it set up right?" or, "I can't figure out why this balloon pump keeps alarming," or, "I'm concerned that I'm missing something here--got any ideas?"
And if a co-workers says, "Hey, that's not how this Swan is supposed to be hooked up," or, "Do you want your dopamine running at this rate?" or "The heating coil should be on this return line," be strong and secure enough not to take it as a personal affront. People who reach out with constructive criticism are trying to HELP YOU. Getting angry and defensive and making stupid excuses will make you co-workers go silent, step back and let you fall.
Take a deep breath and say, "Thanks for catching that!"
Together, we make a great team.
