Hack! Cough! Wheeze! How do you get coworkers to stay home?

If the swine flu taught us anything, it was to stay home when you're sick or the illness will spread. Thankfully, this flu hasn’t become a pandemic yet. But what if it does? Many coworkers come into work no matter how lousy they feel. I understand because no one wants to lose pay, especially in the days of lowered benefits.

With the threat of the flu still out there, should we ask the boss to talk to a coworker who obviously should have stayed home?

How do you catch a credit thief?

At my team's monthly meeting, we discuss current projects, ideas and future work. Last month, a coworker started talking about a successful project and took all the credit himself! This isn't the first time credit thieving has happened. What's the best way to deal with coworkers and managers who take credit for your work, or should you just hope that karma will balance things out?
