But it's the first time they've been caught smoking, which violates one of the playground rules. (It's also a rule, by now, in city parks.)
Atlantic Yards Watch has two sets of photos, one set taken yesterday, with the workers smoking, and another taken June 4, with the workers just hanging out.
Enforcement would seem to be a job for both the Parks Department and the Police Department; according to AY Watch, 311 advised a call to the former.
A few construction workers, at least, do not think rules apply to them; hence the creation of free parking by uprooting a "No Standing" sign.
