If you follow the calculations, Labor & Industry was stating that the piece rates or pounds picked were too high for one person and thus were dividing them in half based upon their assumption that two workers were on one ticket. If half of the production X the rate per pound did not make minimum wage the employer was hit with an assessment.
60 lbs per hour X .28 = $16.80 per hour.
If you divided that in half 30 X .28 = $8.40 and thus the employer must pay a pickup amount on the original and imaginary employee.
$16.80 is not a bad hourly rate for unskilled farm labor.
Sorry, I remembered the rate at .28 when it was .33 per pound.
60 x .33 = $19.80 per hour
