Traditional labor management systems face significant challenges, including delayed wage payments, worker exploitation, and difficulty in verifying employment history. These challenges are particularly common among migrant and freelance workers, who tend to suffer from non-payment and insecurity of employment. Moreover, the current systems are not transparent, and it is hard to monitor project progress, payments, and contractual terms, resulting in common conflicts between employers and workers. This paper introduces a Decentralized Labor Management System (DLMS) that utilizes blockchain technology. DLMS overcomes these by employing smart contracts, where employers first deposit funds before the commencement of work, with automatic payment at the end. This removes delays in wages and risks of non-payment, most especially for migrant and freelance laborers. It also securely stores worker profiles, job histories, and credentials on an immutable blockchain ledger, which allows for verifiable proof of experience and ability. The platform increases transparency by enabling real-time monitoring of projects, payments, and agreements, minimizing fraud and disputes between employers and workers. In times of crisis, like the COVID-19 pandemic, it can enable real-time location and condition monitoring of workers to help organizations and governments offer timely support. Through trust building, removal of financial barriers, and simplification of employment procedures, DLMS enables a more equitable and efficient labor system that favors both workers and employers.
