No — your previously acquired rights are fully protected. Article 4 of Labour Law No. 14 of 2025 explicitly states that the new law does not prejudice any rights that workers had already obtained under previous laws, regulations, systems, agreements, or internal decisions. This means wages, benefits, and entitlements you earned or were granted before the new law took effect remain intact.
Furthermore, Article 4 provides that any rights or obligations that arose under the old law — including the now-repealed Labour Law No. 12 of 2003, which is formally abolished by Article 12 — continue to be governed by the old law's provisions for matters that occurred during its period of application. In other words, the transition to the new law does not retroactively strip you of past entitlements.
As a practical step, it is a good idea to keep copies of your original employment contract, any collective agreements, and any official communications confirming benefits or entitlements you received before the new law came into force. If your employer attempts to reduce your salary, allowances, or other benefits citing the new law, this would be unlawful under Article 4, and you would have grounds to challenge it through the Ministry of Labour or the specialised labour courts.
