They toiled to repair and rebuild the homes, apartments and businesses that Hurricane Sandy damaged. They ran into areas where danger lurked — contaminated water, downed power lines, hidden debris capable of puncturing skin. And while the day laborers of Bay Parkway Community Job Center helped in the recovery of Hurricane Sandy, their own facility laid in shambles. Sandy’s angry, unforgiving winds shook the old center, an 8-by-12 wooden shack, off its foundation, blowing it 100 feet away, causing major damage. But with grants from several foundations and the work of the laborers, the center was brought back to life. It is a renaissance of sorts for the center — now a 40-foot trailer the workers painted in red and yellow, the colors of the old shack — and also a new incarnation for the laborers and their place in the larger community.
