Understanding Co-Employment Liability

In the bustling business landscape of Los Angeles, companies often lean on staffing agencies, contractors, and temporary employees to meet evolving workforce needs. But with flexibility comes legal complexity—particularly in the form of co-employment liability. Co-employment occurs when two or more employers share legal responsibilities for the same employee. In this scenario, both the staffing agency and the client company may be held accountable for employment-related matters like wages, benefits, discrimination claims, and workplace injuries. While this shared responsibility may seem harmless on the surface, it can expose businesses to significant legal and financial risks if not handled correctly.

Common Causes of Co-Employment Liability

Many co-employment issues arise not from intentional wrongdoing, but from simple misunderstandings or poor documentation. Common red flags include companies exercising too much control over temporary workers, failing to clarify who’s responsible for compliance with labor laws, or blurring lines in job responsibilities. For instance, if a client company disciplines or directs a staffing agency’s employee as if they were their own, courts may determine that co-employment exists. Even accidental mistakes—like giving a temp employee access to benefits meant only for full-time staff—can raise legal concerns. Identifying these risk areas early is key to staying protected.

The Importance of Clear Employment Contracts

Contracts are your first line of defense. Whether you’re working with a staffing agency or engaging independent contractors, your contracts should clearly define the nature of the relationship. Include detailed responsibilities, who manages day-to-day supervision, and who handles payroll, benefits, and HR compliance. Avoid vague language that might make it seem like the staffing agency worker is a direct employee of your company. At Carbon Law Group, we’ve seen too many disputes arise because of templated agreements that don’t account for co-employment risks—customization and clarity are essential.

Best Practices for Employee Classification

One of the fastest ways to invite legal scrutiny is by misclassifying workers. The difference between an independent contractor and an employee goes far beyond a job title—it involves behavioral control, financial control, and the nature of the relationship. Misclassification can lead to back taxes, penalties, and wage claims. The IRS and California’s Employment Development Department (EDD) take this seriously, and so should you. We advise every business to review their classifications regularly and use clearly defined criteria to distinguish contractors from employees.

How to Maintain Proper Control Over Workers

Many business owners unintentionally create co-employment risk by exercising too much control over workers supplied by a staffing agency. It’s tempting to treat these workers as part of your team—but legally, that can be problematic. Avoid managing performance reviews, assigning tasks outside of the original contract, or directly handling discipline. Instead, communicate through the staffing agency and allow them to manage their own workforce. This not only respects the legal boundaries but also reduces your exposure to liability.

The Role of Independent Contractors in Co-Employment

Independent contractors offer flexibility, but they come with their own legal risks—especially in California. The state follows the ABC test to determine whether a worker is truly an independent contractor. If your business controls how the work is done, the person performs work that’s integral to your business, or they don’t have a separate established trade, the IRS or EDD may reclassify them as an employee. Be cautious when hiring “contractors” who work like employees—it’s often safer to bring them on with the right employment classification and protections in place.

Training and Communication Strategies for Employers

Even with airtight contracts, training your internal team is essential. Supervisors and managers need to understand what they can and cannot do when working with agency employees or contractors. Create internal policies that outline acceptable interactions and make sure your staff knows who to contact if issues arise. Open communication with your staffing partners is just as important. Align on expectations, reporting protocols, and legal responsibilities from the beginning of the engagement. This avoids confusion and helps prevent accidental overreach.

Legal Obligations and Compliance Requirements

Los Angeles businesses must also stay on top of ever-changing employment laws. California’s labor laws are some of the strictest in the country, including wage and hour laws, anti-discrimination protections, and specific rules about joint employment. Failure to comply can result in audits, lawsuits, and fines. Make sure you’re up to date on requirements from the California Labor Code, the Fair Labor Standards Act (FLSA), and recent case law involving joint employment and co-employment. Working with a business attorney helps ensure your practices remain compliant and current.

When to Seek Legal Advice from a Business Attorney

If you’re unsure about the nature of a work relationship, it’s time to get legal guidance. A knowledgeable business attorney can help you evaluate risk, draft or revise contracts, and develop training protocols that align with state and federal law. They can also represent you if a dispute arises, giving you a strategic advantage. Waiting until a lawsuit is filed is too late—legal counsel should be part of your proactive risk management strategy. Especially in high-risk areas like staffing and labor law, preventative legal advice saves time, stress, and money.
