How much leave, and its cash value
Paid annual leave accrues by tenure, and unused days can be paid out as a leave allowance.
Days: under 1 year earns 1 per full month (max 11); from 1 year it is 15 days, plus 1 more every 2 years from year 3 (max 25) — so 16 at year 3, 17 at year 5, reaching 25 around year 21.
Allowance = daily ordinary wage × unused days, where daily wage = monthly ordinary wage ÷ 209 × 8. Note ordinary wage isn't your full salary, and lawful leave-use promotion can extinguish the allowance. See the severance calculator or salary calculator.
