California Labor Commissioner’s BOFE Unit Cites Janitorial Companies and OptumCare for $468,204 in Wage Theft Violations
Los Angeles— The California Labor Commissioner’s Office (LCO) has cited several janitorial companies, their owners, and OptumCare Management LLC $468,204 for wage theft violations affecting over 90 janitors who cleaned manufacturing, laboratory, and healthcare facilities across Los Angeles and Orange counties.
An investigation by the LCO’s Bureau of Field Enforcement (BOFE) determined that workers were denied minimum and contract wages, overtime pay, split shift, meal and rest period premiums, and were issued inaccurate wage statements.
The investigation 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.

What California Labor Commissioner Lilia García-Brower said: “This case is a clearcut example of how bad actors, intent on undercutting their employees and pocketing money for themselves, used multiple business names to obscure accountability. California labor laws ensure that when workers are cheated, the businesses that profit from their labor share in the responsibility and are held accountable.”
Investigators determined that these entities were used as alter egos to avoid liability and that OptumCare, which benefited from the janitors’ work, 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. This law prevents companies from escaping accountability when they rely on contractors who underpay or exploit workers while performing core services essential to their operations.
The investigation began after the Maintenance Cooperation Trust Fund (MCTF), a janitorial watchdog group, referred the case to the LCO in 2019. Following the referral, BOFE launched an investigation that found janitors cleaning facilities during both day and night shifts, 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 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.
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.
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.
On October 21, 2025, the LCO issued a Notice of Final Findings affirming $468,204 in unpaid wages, damages, penalties, and interest owed to janitors.
About the Bureau of Field Enforcement
BOFE is a unit within the LCO enforcing key labor laws through on-site investigations and strategic enforcement actions.
BOFE targets industries with high rates of labor violations, conducting workplace inspections to uncover wage theft, child labor violations, failure to carry workers’ compensation insurance, and other unlawful employment practices. Its work helps ensure fair treatment for workers while promoting a level playing field for responsible employers.
BOFE has issued more than 2,200 citations against employers for labor law violations between January 2022 and November 2025, recovering over $49.1 million in stolen wages, damages, and interest on behalf of workers.
This comes on top of multiple announcements this year highlighting a range of violations, including a settlement of $431,601 to return unpaid wages and damages to 86 carpenters, $1.1 Million in penalties issued to a Buena Park restaurant over wage and sick leave violations, and a citation of over $2 million for another case of misclassifying workers.
BOFE has also issued more than 3,300 notices to discontinue labor law violations in the past year, and corrected violations that collectively impacted more than 42,000 California workers.
To meet growing enforcement demands and expand outreach, BOFE has also increased staffing across key regions, strengthening its presence in communities most impacted by labor violations.
