Is plywood taken from job site 'above board'?

Framers who cart off materials may have valid explanation

DEAR BARRY: I’m not sure if this is a question for you, but here goes. My son is having a house built. Yesterday while approaching the location of the lot, I observed the house framers loading good pieces of plywood in their truck. Since this was at the end of the workday, I assume that they were taking the wood for their personal use. Is it legal for them to do this? Or should I report this action to the builder? –Joel

DEAR JOEL: There are other possible explanations for the framers having removed materials from the property. For example, the plywood they were loading may have been surplus that the builder intended to use on another project.
