Contractor worker accreditation

Event: contractor_worker.accreditation.

One notice is sent per contractor worker and work center when the worker changes between accredited and not accredited in that work center. The new state is in accreditation.status: approved or revoked.

Accredited

A contractor worker is accredited in a work center when:

• the contractor is enabled and the worker is active,
• the contractor has a worker certificate assigned, and
• every required document is uploaded, validated for that work center and not expired:
  • the documents of the contractor's worker certificate (the worker's own documents),
  • the documents of the contractor's own certificate,
  • for each active contract of the worker that includes the work center, what the contract requires from its workers, from the worker's position and from the contractor.

Supply and machinery documents don't count.

When it is sent

Tazki reviews the worker whenever something that affects the result changes: a document is validated, rejected, deleted or expires, a requirement is added or removed, a contract starts, ends or changes, the worker is activated, deactivated or changes position, the contractor is disabled, and so on. A notice is sent only when the result of that review differs from the last state notified for that worker and work center.

• First review. The first time Tazki reviews a worker in a work center, it only records the state and sends nothing, even if the worker is accredited. Notices start with the next change.
• New work center. A worker that Tazki already knows and that joins another work center gets an approved notice if they are accredited there right away. If they are not, nothing is sent (they were never accredited there).
• Expirations are checked daily, shortly after midnight (Chile time): a worker whose document expired the day before gets a revoked notice.
• Validating one document doesn't send anything while other required documents are still missing.
