Worker classification and accountability.

Establishes a presumption that individuals providing labor for certain government supported projects are employees. Specifies that the general contractor for these projects is jointly liable with any subcontractor or professional employer organization for penalties and unpaid taxes or deposits with a governmental entity resulting from failure to comply with any law, regulation, ordinance, or contract provision requiring licensing, bonding, insurance or self-insurance, or misclassification of an employee as an independent contractor. Provides a procedure for an interested person to initiate an investigation of a violation.
