Difficulty: Moderately Easy
Step1
Be willing to listen. Let your grumpy coworker vent. She may be having difficulty with another employee, a task or a client that you can help to resolve. Or lend an ear if she wants to talk because she's in a funk or having a personal problem.
Step2
Make a simple gesture like buying your coworker a cup of coffee, bringing flowers for her desk, paying her a compliment or writing an upbeat note. Just the fact that you thought of her may brighten her day.
Step3
Ask if you can help ease your coworker's workload in any way. Clearing off a cluttered desk or cutting the stack in an inbox may reduce his stress and lighten the mood.
Step4
Get him to laugh. Tell a joke, recount one of your most embarrassing moments or tell him about something funny you just saw in the break room.
Step5
Ensure that your coworker isn't grumpy because you're pestering her. Take the hint and stop trying to cheer her up if she seems eager to get back to work.
