Annual leave entitlement: workers accrue paid leave and may encash or carry forward unused leave under specified conditions. Every worker is entitled to annual leave with wages upon working 180 days in a calendar year, accruing one day's leave per twenty days worked (fifteen days for adolescents and below-ground mine workers). Periods of layoff, maternity leave or prior annual leave count toward the 180-day threshold but do not earn leave; mid-year entrants qualify after working one-quarter of the remainder of the year. Wages in lieu of accrued leave are payable on termination, resignation, superannuation or death; unused leave may be carried forward up to thirty days or, if leave was refused after application, without limit. Workers may encash leave at year-end and encash amounts exceeding thirty days. The appropriate government may extend these rules to other establishments (excluding railways), and more favourable mine-specific provisions prevail, with exemption powers where alternate rules are not less favourable.
