Daily wages are calculated at a basic rate or gross rate of pay.
Basic rate is used in calculating work on rest days or public holidays, excluding any additional payments e.g. allowances, bonus, reimbursements, incentives.
Gross rate is used in calculating paid public holidays, paid leave (e.g. annual leave, hospitalisation leave), salary in lieu of notice of termination and salary deductions for absence from work. This includes allowances (except for travel, food & housing allowances) but excludes other additional payments.
