I used to employ kids after school as 'floor sweepers' at $10 p/hr cash (not much, but these kids appreciated the cash & it was also over 10 yrs ago). If they proved themselves over a period of time they were first in line for an apprenticeship.
This worked well for all involved until a mum came in one day with her son & asked about workcover, super & groupl cert. for her 14yo kid...that was the end of that setup & myself & employees had to get back on the broom themselves.
