Stop Work Authority is the right of any employee to halt work if they identify an unsafe condition or practice.
A policy empowering every worker — regardless of position — to stop a task or operation without fear of retaliation when they believe it poses an imminent risk to health, safety, or the environment, until the concern is addressed.
A crane operator notices a rigging configuration that looks unstable and invokes stop work authority, pausing the lift until a supervisor reviews and corrects the rigging.
The core principle is that any employee, regardless of role or seniority, can exercise stop work authority when they perceive a serious hazard.
Organizations with genuine stop work authority policies commit to non-retaliation, and in many jurisdictions, workers also have legal protections for refusing unsafe work under whistleblower or occupational safety laws.
Stop work authority is typically a proactive, organization-endorsed program encouraging intervention at the first sign of risk, while the right to refuse unsafe work is often a baseline legal protection invoked when a worker faces a specific hazard.
