What Is the OECD EPL Database?
The OECD Employment Protection Legislation (EPL) database is a systematic measure of the rules governing how and when employers can dismiss workers across member and partner economies. The OECD has been collecting these indicators since the early 1990s, making it one of the most consistent cross-national datasets on labour market regulation available.
Employment protection laws vary enormously by country. In some countries, dismissing a permanent employee requires months of notice, substantial severance pay, and approval from labour authorities. In others, at-will employment means a worker can be let go with little notice and minimal compensation. The EPL database translates these legal differences into comparable numeric scores.
The 0–6 Scale Explained
All EPL indicators use a scale from 0 to 6, where:
- 0 indicates no legal restrictions, the most flexible labour market regime
- 6 indicates the maximum legal protection, the most restrictive regime
Scores are derived from detailed information on legal provisions: notice periods (in weeks), severance pay (in months of wages), procedural steps required before dismissal, grounds required for fair dismissal, and reinstatement rights. The OECD converts these specific legal rules into sub-indices, which are then aggregated into pillar scores and an overall index.
No country scores 0 on every dimension, even the least regulated economies have some procedural requirements. Equally, no country reaches 6 across the board; the highest overall scores in the dataset sit around 3.5.
The Three Pillars
The overall EPL score is built from three distinct pillars, each measuring a different aspect of employment protection:
Pillar 1: Protection of Regular Employment
This pillar covers the rules for dismissing a permanent employee on an individual basis. It includes:
- Procedural requirements (written notice, notification of authorities, opportunity for the employee to respond)
- Notice periods at 9 months, 4 years, and 20 years of tenure
- Severance pay at 9 months, 4 years, and 20 years of tenure
- Difficulty of dismissal (grounds required, reinstatement if unfair, compensation if unfair)
- Length of probationary period
Regular employment protection is the pillar most directly relevant to decisions about hiring permanent staff.
Pillar 2: Regulation of Temporary Employment
This pillar captures restrictions on fixed-term and temporary agency work. It measures:
- Valid reasons for using fixed-term contracts (whether employers must justify their use)
- Maximum number of contract renewals
- Maximum cumulative duration of fixed-term arrangements
- Restrictions on temporary agency work (types of work allowed, maximum duration)
Countries with strict temporary employment rules, like France and Spain historically, limit employers from using revolving short-term contracts as a way to avoid permanent employment obligations.
Pillar 3: Specific Requirements for Collective Dismissals
This pillar applies when an employer dismisses a large number of workers simultaneously, such as during a restructuring or plant closure. It covers:
- The threshold number of workers that triggers collective dismissal procedures
- Additional notification requirements (works councils, labour authorities)
- Additional delays beyond standard individual notice periods
- Other obligations (social plans, outplacement services)
Collective dismissal rules matter most to large employers and multinational companies planning workforce reductions.
How the Overall Score Is Computed
The OECD overall EPL score is a weighted average of the three pillars. The weighting scheme gives greater emphasis to regular employment protection (pillar 1) and somewhat less to collective dismissals (pillar 3). The exact weighting is documented in the OECD methodology paper and has remained broadly consistent across updates, allowing for historical comparisons.
Where this plays out today
Across the 72 countries PlainEmploy currently tracks on this index, Indonesia scores highest at 4.08/6, the median is 2.32/6, and Costa Rica scores lowest at 0.85/6, see the full OECD overall ranking for where every reporting country falls between them. These figures are pulled live from the same dataset every other PlainEmploy page uses, so they move if the OECD publishes a revision.
When comparing countries, it is often more useful to examine individual pillar scores than the overall index. A country might have moderate overall protection but very high temporary contract restrictions and very low regular employment protection, a pattern with very different implications for workers and employers than the aggregate number suggests.
Coverage and Limitations
The OECD EPL pillar described in this guide covers 72 countries, with the most recent data from 2019. PlainEmploy combines this with two other sources, ILO EPLex (95 countries) and World Bank B-READY (101 countries) - for a total coverage of 145 unique countries. Several important limitations apply to the OECD EPL data specifically:
- Law vs enforcement: The EPL database scores what the law says, not how it is enforced. Countries with strong laws but weak enforcement mechanisms may have lower effective protection than their score suggests.
- Informal economy excluded: Workers in informal or unregistered employment, a significant share of the workforce in many developing economies, are not covered by these laws.
- Collective bargaining not captured: Sector-level agreements negotiated between unions and employer associations can significantly modify employment conditions but are not reflected in EPL scores.
- Data lag: Legal changes enacted after 2019 are not reflected. Countries that have reformed their labour laws in recent years may have different current scores.
How to Use This Data
The EPL scores are most useful as a starting point for understanding the regulatory environment in a target country. Before making hiring or expansion decisions, consult local legal counsel to understand current law, enforcement patterns, and any sector-specific collective agreements that may apply to your workforce.
