Every position with names and headcount by season, the crew leads between the manager and the seasonal crew, the months each layer works, and the same structure for the U.S. affiliate on the transfer date and a year later.
Draw the chart the business uses, then annotate it with dates
The chart is the deciding document for the managerial question, so it must be accurate and legible. Show the owner or board, the general manager, the grower and maintenance lead, the crew leads, and the seasonal crew as a block with its headcount and its months of work. Add the manager's own line, indicating who he reports to and whether the owner is active in operations.
Attach a monthly payroll summary that lets the officer see the seasonal swell and confirm that crew leads are paid as such. For the U.S. affiliate, provide two charts: one on the day he arrives and one projected for twelve months later, with the hiring plan behind it.
Keep job titles identical across the chart, the payroll and the support letter. If the business has an old chart that differs, explain what changed and when; do not quietly replace it.
