This is what immigration have on their website:
What is skilled employment?
Skilled employment is employment that requires specialist, technical or management expertise.
If you have a job/job offer for skilled employment, it must be:
full time (on average, at least 30 hours per week)
for a position that is paid by salary or wages or in terms of a contract for service – payment by commission and/or retainer are not acceptable
be ongoing and sustainable.
My question is:
Anybody knows what "payment by commission and/or retainer" means??
Cheers
