There shall be withheld from each weekly payment of wages or salary from said worker an amount equal to forty per cent of the insurance premium payable on said policy, the employer to contribute the remaining sixty per cent. Said employer shall then pay the entire premium when due to the insurer. If an employer or grower fails to withhold from such worker's wages the weekly sum as aforesaid, he shall be liable for the payment of the entire premium. If the worker is disabled for a full week and is unable to work for said week the employer shall pay the entire cost of the premium for that week.

Said term shall not include students regularly enrolled in institutions of secondary and higher learning nor shall it include a worker who is covered by a family medical plan.
