When a crew member has not uploaded a qualification or if their current one expires, they will be blocked from the specific activity in which the qualification is needed. Blocking crew from specific activities allows crew members to work on shifts where the specified activity isn’t being carried out.
For example, a crew member’s heavy vehicle drivers licence may expire. This will block them from being offered any activity of a job/shift that requires a valid heavy vehicle licence. However, the crew member will not be blocked from being offered general activity shifts, rigging, lighting, forklift driving etc. This form of blocking is implemented to ensure that all crew are being utilised, while encouraging the renewal of documents in order to practise work legally.
