Employment letters from both group companies with precise dates, payroll and tax slips covering the entire period, organizational charts naming his subordinates, and corporate records showing the two companies were related throughout. The payroll records should reconcile across the transfer month.
Ordinary payroll paperwork proves more than a written narrative
Petitions of this kind are usually won or lost on documents nobody thought to keep tidy. Start with the two employment letters, each stating the exact start and end date, title, reporting line and duties, signed by someone with authority in that company. Add payroll registers or the annual tax slips for both employers so that every month of the twenty-two is covered by a record from one of them.
Where the payroll switched partway through a period, obtain the final and first pay statements so the join is visible. Then prove capacity: an organizational chart with real names and titles for each period, offers of employment Bertrand signed, a maintenance budget he approved, minutes of a management meeting he chaired. Written job descriptions drafted for the petition read as advocacy unless the underlying records support them.
