Tokyo- Higher-paid individuals with specialized skills and low-wage workers in need of additional income to make ends meet tend to take on second jobs more than middle-class workers, a government survey showed.
Among employees of different income classes, 6.25 percent of those earning 10 million yen or more a year in their main jobs had side jobs in 2022, with the proportion even higher for individuals earning 15 million yen or more, according to the Employment Status Survey by the Ministry of Internal Affairs and Communications.
