job and knock
n.— «A regular inquiry theme has been the RailCorp tradition of “job and knock”—a term for leaving a job after only a couple of hours but charging for the whole day.» —“Employee goes back to work despite theft, fraud” by Linton Besser Sydney Morning Herald May 10, 2008.

Hi,
My (UK) understanding of the term is somewhat different. Here “job and knock” means being paid a day’s wage for doing a specific job, regardless of the time taken – an incentive to the hourly-paid to get a job done quickly: finish the job and knock off.
