Each Monday we welcome you back to the work week with a look at what to expect in the Chathams. From content you'll find on Patch as the week goes on to community activities, here's what you need to know this week:

1) You need to know about Chatham High School graduates: We'll bring you a profile of what the class of 2012 is up to now, courtesy of the school district.

2) You need to know about new businesses: We'll bring you a profile of Aida's Cozy Kitchen, a new business in town but one with familiar roots.

3) You need to know about the arts: Chatham Middle School and Chatham High School have upcoming musical productions, and we'll bring you a preview of both.

4) You need to know about local concerts: We'll bring you a preview of the upcoming Sanctuary Concert Series, along with a ticket give-away.
