The PCBU does not direct or allow a worker to carry out licensed high risk work without seeing written evidence of the relevant licence, to do it as a trainee without evidence of enrolment in the training course, to do it under the 60-day VET certification exception without evidence of the certification and, where relevant, of the licence application, or to supervise it without evidence of the supervisor's licence; the PCBU keeps a record of that evidence for at least 1 year after the work (or the last supervision).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
