California Labor Commissioner Cites Janitorial Companies, OptumCare $468K

The California Labor Commissioner’s Office has cited several janitorial companies, their owners, and OptumCare Management LLC $468,204 for wage theft violations that reportedly impacted more than 90 janitors who cleaned manufacturing, laboratory, and healthcare facilities across Los Angeles and Orange counties.

According to an investigation by the LCO’s Bureau of Field Enforcement, workers were denied minimum and contract wages, overtime pay, split shift, meal and rest period premiums, and were issued inaccurate wage statements.

The investigation reportedly found that Winsor Maintenance Inc., Winsor Services Inc., Main Source Group Inc., Main Source Global Inc., Main Source World Inc., and Top Building Material & Supply Inc. operated as a single enterprise controlled by multiple members of the Hong family – Sunkee “Charles” Hong, husband, Michelle Hong, wife, and Hannah Hong, daughter, along with family friend Suchin Yi.

Janitors worked for years at the same job sites, reported to the same supervisors, and even wore uniforms labeled “Main Source,” yet their pay stubs listed different company names, according to investigators, who say the Hong family and Yi used several connected companies to conceal who was truly responsible for paying workers.

According to investigators, these entities were used as alter egos to avoid liability, and OptumCare is also responsible as a client employer under Labor Code section 2810.3, which holds businesses that obtain labor from subcontractors jointly liable for wage theft and other labor law violations committed.

The investigation began after the Maintenance Cooperation Trust Fund, a janitorial watchdog group, referred the case to the LCO in 2019. Following the referral, an investigation found janitors cleaning facilities, often working beyond scheduled hours without overtime pay. Workers were also not compensated for time spent traveling between job sites, and many were denied meal and rest breaks due to excessive workloads, investigators say.

Investigators also found that pay stubs were incomplete, lacking required information such as hourly rates, total hours worked and deductions. In several cases, workers were not paid all wages owed at the end of their employment, according to investigators

Citations were issued in 2021 to the janitorial companies, members of the Hong family, and Suchin Yi, as well as several businesses that hired the janitors through those companies. Some of these client employers reached settlements before the 2024 hearing, while the direct employers, individuals, and OptumCare proceeded to a 14-day administrative hearing, according to the LCO.

During the proceedings, Winsor Maintenance, Inc., Main Source Group, Inc., and Yi filed for Chapter 7 bankruptcy on December 4, 2024. Yi was discharged in May 2025, but corporate debts remain outstanding under bankruptcy law, leaving the companies liable for unpaid wages and penalties.

The LCO is a division of the California Department of Industrial Relations.
