Work systems

Find SUIDs for Japanese work hour systems and labor arrangements in the Job Sync API.

 

Overview

Work system SUIDs classify working-hour arrangements under Japanese labor law. They help job seekers understand each role's schedule structure and flexibility.

Work systems include:

• Fixed working hours: standard set schedule with consistent hours
• Flexible arrangements: flextime, variable hours, and shift systems
• Discretionary systems: professional or planning work with flexible hours
• Deemed working hours: work outside the office where hours are hard to track
• Highly Professional System: specialized high-income professionals

Example usage

Specify work system SUIDs in the attributes field of the SourcedJobPostingTaxonomyInput object:

mutation CreateJobPosting {
  jobsIngest {
    createSourcedJobPostings(input: {
      jobPostings: [{
        body: {
          title: "Software Engineer"
          description: "<p>Join our engineering team...</p>"
          location: {
            country: "JP"
            cityRegionPostal: "Tokyo"
