The issues for NTC and NMW are closely linked. When you are
considering whether the claimant(s) has met the minimum hours
qualification (cross-reference CCM Chapter 6 - Particular Aspects -
Work and Hours
CCM6630 et seq.) for WTC, the hourly rate
at which the claimant(s) has apparently been paid will be an
important factor in your conclusions. If, when you have established
to your satisfaction the number of hours worked, the hourly rate
appears to be less than the NMW, you will have a strong indication
that the employer has failed to operate the NMW requirement (though
not conclusive proof, as the hourly rates for NTC and for NMW may
legitimately be calculated on different bases).
You should pass on this intelligence to the CCRO, who will
refer it on to the NMW team, without yourself getting involved in
any discussions with the employer.
