Mermaid Beach Hotel Ltd (Mermaid Hotel) operates a seaside hotel on the Sunshine Coast, providing accommodation, bar and restaurant facilities for tourists. Casual and part-time wages are a major expense item, particularly during summer, when up to an additional 30 staff members are employed. In order to keep track of casual and part-time wages, Mermaid Hotels operations manager prepares a weekly roster (using Excel) showing: employee name employment position (e.g. bar staff) days and hours rostered for the week hourly rate any additional amounts to be paid (e.g. meal allowances). Each employees immediate supervisor is required to sign a hard copy of the Excel roster spreadsheet on a daily basis as evidence that the hours were worked as rostered. Any discrepancies (e.g. additional hours) are recorded on a separate payroll adjustment form (PAF) and co-signed by the employee. The Excel roster spreadsheet plus any PAFs are forwarded to the payroll officer at the end of the week and used as the basis for that weeks casual and part-time employee payroll.
