Seniority Indemnity Calculation Errors
Risk Level: HIGH
Cambodia's mandatory seniority indemnity (7.5 days per 6 months) must be paid twice yearly to all employees regardless of contract type. The calculation base includes basic wages plus seniority from previous cycles. Many foreign employers are unaware this replaces (not supplements) traditional severance. MLVT inspections are frequent in manufacturing. Ontop calculates and schedules seniority indemnity payments automatically every 6 months.
Determined Duration Contract (DDC) Abuse
Risk Level: HIGH
Cambodian law permits DDC only for specific temporary activities. The maximum DDC duration is 2 years including renewals. Chaining multiple DDCs for the same role triggers automatic permanent employment conversion. MLVT has increased DDC compliance inspections since 2023. Ontop tracks DDC duration and flags conversions before the 2-year limit is reached.
