Given the evidence that the move was an attempt to avoid obligations under the CBA, employer's shift of a group of employees to a subcontractor was simply a disguised continuance of the business, and the protections of the CBA continued, whatever the technical employment status of the employees.

CBA counts lunch half-hour as time actually worked, as it is compensated.
