Yes, Saudi Labor Law explicitly protects subcontracted workers. Article 11 states that if an employer assigns all or part of their original work to another person (a subcontractor), that subcontractor must give their workers all the rights and privileges that the original employer provides to their own workers.
This is a significant protection because it prevents a two-tier system where subcontracted workers receive inferior terms compared to directly employed staff on the same project. Your wages, working hours, rest periods, and other entitlements should be equivalent to those of the main employer's workforce.
In practice, if you believe your subcontracting employer is providing fewer rights or benefits than the main contractor's employees receive, you can raise this with the Labor Office. It is advisable to find out what terms the primary employer offers — through official documentation if possible — as this sets the benchmark for what you are entitled to. Always ensure your own employment contract with the subcontractor is in writing and in Arabic as required by Article 9.
