Last month, Apartment Investment and Management Company (Aimco) turned a typical week at the office into a massive do-good campaign across the country. From building homes to maintaining park trails and filling shelves at a food pantry, Aimco workers chipped in to give back to the communities they live and work in. Call it corporate citizenship. Call it philanthropy. We’d like to call it a challenge: Tell us in the comments about other companies that are doing the right thing. —Natasha Gardner
