Internal records that only the employer could produce. Training curricula naming the employee, method or standard documents he authored, revision histories, records of him instructing others, evidence of a wage differential reflecting the knowledge, and any patent or trade-secret register entry connected to the work.
Assemble what an outsider could not have
Hypothetical example: Julien's file consists of a two-page resume and a manager's letter praising his contribution. Nothing in it distinguishes him from a capable hire in the same field, which is precisely the conclusion an adjudicator will reach. The petition needs material generated inside the business.
Internal training curricula that name him as author or instructor show the knowledge is the company's and that he holds it at an advanced level. Method documents, work instructions and their revision histories show authorship and date. Records of him training colleagues, with attendee lists, show the knowledge is not commonplace even within the firm.
Payroll evidence that his compensation exceeds the band for the same job title elsewhere in the company supports the claim indirectly. Where the employer cannot produce any of this, that absence is itself the answer, and it is better learned before a fee is paid than after a refusal.
