by which the worker's earnings for that four-weekly measure-up period are
less than either the sum of 160 times the hourly day-wages rate for a
labourer or 160 times the average hourly earnings rate for that period,
whichever is the lower.

(c) (i) Notwithstanding the provisions of subclause (a) above, provided
a youth has worked full time (other than time lost through wet weather)
he shall be paid the amount (if any) by which his earnings for such period
are less than the sum of 80 times the minimum hourly rate for his age.
(ii) A youth receiving adult rate of pay shall be paid for wet time as
prescribed in subclauses (a) and (b) above.

3d. an hour.

(e) When a worker loses time through his own default or for any reason
other than wet weather the minimum payment prescribed in subclauses (a),
(b), and (c) above shall be reduced by an amount equal to a labourer’s hourly
rate of pay (or appropriate rate in the case of a youth) for every hour so
lost. A similar reduction shall be made when a worker starts, leaves of his
own accord, or is discharged.
(f) A worker shall be deemed to have lost time through his own default
if he—
(i) Refuses to work after the officer in charge (or other authorized
person) has decided that work shall continue; or
(ii) Does not report for duty on a wet day; or
(iii) Leaves the work on a showery day without the permission of the
officer in charge or other authorized person.
(g) The officer in charge (or other authorized person) shall be the sole
judge whether or not a day, or part of a day, is too wet for working. Any
time during which a worker is required to remain on the job when he is unable
to work because of wet weather shall be deemed to be time worked.
(h) Where practicable, workers shall make up time lost through wet
weather by working not more than one hour a day extra time on Mondays
to Fridays inclusive. A worker refusing to do so shall be deemed to have
lost time through his own default. Payment for such extra time worked
shall be at ordinary time rate only, notwithstanding the provisions of clause 6
hereof.
(i) If during a fortnightly pay period (or four-weekly measure-up period
in the case of a co-operative contract worker) a worker has not been able to
make up the whole of the time lost in that period, he shall not be required
to make up the balance during a subsequent period.
(j) Time lost through wet weather by co-operative contract workers shall
be paid for at the end of the four-weekly measure-up period.
