Happy Halloween!

Well, there's nothing spooky or macabre about this week's theme. In fact, it really comes down to just two simple letters: C and O. Put these letters side by side and they mean "together", which explains why we like to call the four words we're introducing this week "The Four Cs of Teamwork." Letters working together, people working together - sounds like a great way to do business!
