Nothing keeps a person accountable like a signature. That John Hancock still carries the same weight it did back in 1776.
When the collapse of a Bangladesh garment factory killed over 1,100 workers last month—and eight more perished in a fire at another clothing factory soon after—astonishingly, the clothing retailers tied to these tragedies claimed to know nothing at all about where their merchandise is made or under what conditions. Of course, such ignorance (along with cost savings) is one of the virtues of contracting out: You can always deny knowing anything about what your contractors or subcontractors are doing.
