Organisation of Working Time Act, 1997, Section 20
This link mentions holiday pay. We are told that the 'contractors' are forced to take a month off, unpaid, and often not of their choosing. Given that an employee is entitled to a months holiday pay based upon an average of a month's income, I would have thought this would be sufficient incentive for contractors to establish once 7 for all their true status. Not to mention all the other worker's right, including sick day.
