Understanding Overtime Claims in Side Jobs: Key Insights and Legal Implications

Understanding Overtime Claims in Side Jobs



In recent years, the gig economy and side jobs have become increasingly prevalent. However, many individuals and companies remain unaware of the complications that arise concerning overtime claims. A common misbelief is that if an employee's primary job does not entail overtime pay, they are safe from unexpected costs associated with their side jobs. This assumption can lead to significant financial pitfalls.

Combining Working Hours



Under Japan’s Labor Standards Law, the total working hours from both a primary job and side jobs must be aggregated, and if they exceed eight hours in a single day, it is classified as overtime. This means that employers are required to compensate for the overtime hours, especially if the employee has already agreed to work additional hours.

Legal Obligations



Employers of side jobs are often left unaware of their responsibilities without proper validation of an applicant's side job status during the hiring process. A lack of communication regarding the total hours worked can inadvertently lead to a hefty overtime bill for the main employer. This scenario underlines the necessity for companies to actively inquire about prospective employees' side jobs and how they may impact their primary employment obligations.
