The structural vulnerability in healthcare staffing is the joint employer problem. Healthcare staffing agencies supply nurses, CNAs, therapists, and other clinical staff to hospitals and skilled nursing facilities that the staffing agency does not own, operate, or control. But the staffing agency is the employer of record, which means it is liable for Labor Code violations that occur at client facilities where it has no operational authority.

The PAGA exposure is acute because the violations are systematic. CDPH staffing ratios create scheduling constraints that make compliant meal period provision structurally difficult at many facilities, but the staffing agency cannot unilaterally change the facility's scheduling practices. When a county hospital's charge nurse tells a staffing agency nurse that she cannot leave the floor for a meal break because the unit is at minimum staffing, the staffing agency bears the PAGA penalty for a violation it could not have prevented.

The novel defense I developed in one healthcare staffing matter argued that where the alleged violations arise from working conditions controlled by an immune public agency employer, and the staffing firm is a secondary employer without operational authority over those conditions, PAGA penalties should not attach to the staffing firm for those specific violation categories. This required distinguishing between violations attributable to the staffing firm's own payroll and administrative obligations — wage statements, timely payment, expense reimbursement — and violations attributable to the agency's worksite operations — meal timing, rest period scheduling, overtime resulting from facility-mandated shift extensions.
