Stop-work authority has been an integral part of safety for decades now. And for good reason. Giving employees the power – and the expectation – to stop a job when something isn’t right is a cornerstone of a strong safety culture. It prevents injuries, protects equipment, and reinforces a simple truth: production never outranks safety.
But there’s an uncomfortable reality in that framing. By the time we’re stopping work, we’re already in the job.
What if safety didn’t start with stopping?
What if it started with deciding whether we’re truly ready to begin?
That’s the bedrock idea behind adopting a start-work authority process.
Start-work authority treats the beginning of a task as a deliberate decision point, not an automatic reflex. Work doesn’t start just because it’s scheduled. It starts because the conditions are right, the risks are understood, and the people and equipment are ready.
Let’s take the industry of aviation as an example. Before a plane ever leaves the ground, pilots don’t rely on memory or assumptions – they use checklists. Systems are verified. Conditions are reviewed. Readiness is confirmed. The question isn’t “Can we deal with a problem if it shows up?” It’s “Have we done what we need to do to make sure we’re actually ready to go?”
Start-work authority brings that same discipline into everyday work.
A strong start-work authority process usually covers four big areas:
1. Task readiness
Supervisors help make sure the team actually understands what’s about to happen. What’s the scope of the job? Is it routine, or has something changed – tools, location, timing, materials, or people? Clarifying the plan up front prevents quiet assumptions from turning into real hazards.
2. Hazard awareness
This is where supervisors set the tone for what “good” looks like. They don’t just ask, “Any hazards?” They help guide the conversation: Where’s the line of fire? What energy is involved? What’s different today? What could realistically go wrong? Their role isn’t to have all the answers – it’s to make sure the right questions get asked before work starts.
3. Control and equipment readiness
This is the “checklist” part of start-work authority. Supervisors verify that machines are in the correct starting condition, guards and safety devices are in place, lockout or permits are applied when required, and the work area is actually ready for the task. Just like a pilot wouldn’t skip a pre-flight check, we shouldn’t skip confirming that the system is truly safe to operate.
4. People readiness
Yes – this matters too, but it’s only one piece of the whole. Supervisors confirm that employees have the right PPE for the job (not just some PPE), that clothing and hair are appropriate for the task, and that the person doing the work is trained and confident for what they’re about to do. If the job changes, the readiness check changes with it.
When supervisors are engaged in all four areas, start-work authority becomes more than a quick PPE check—it becomes a shared decision that the job is ready to begin.
This is also where start-work authority pairs naturally with stop-work authority. Stop-work authority protects people when conditions change, or something is missed. Start-work authority reduces the chances that you step into a bad situation in the first place. One prevents bad continuations. The other prevents bad beginnings. Both depend on visible, consistent leadership.
So how do you make this real?
1. Set the expectation that work doesn’t start by default.
Leadership needs to consistently reinforce that starting work is a decision, not a habit. A brief pause, huddle, or start-work check becomes the normal way work begins – not an exception when something feels wrong.
2. Give teams a simple, practical structure.
Think “pilot checklist,” or simple “pre-task.” A short list of prompts – task, hazards, controls, people – gives supervisors and crews a shared way to confirm readiness without having to try and remember everything.
3. Build it into everyday supervision.
Start-work authority should show up in how leadership plans work, checks conditions, and talks with their teams before the job begins. When leaders routinely verify readiness – and not just speed – it sends a clear message about what really matters.
4. Back it up and connect it to stop-work authority.
When a supervisor or employee says, “We’re not ready yet,” that pause has to be supported – every time. That means work does not start. We should never hear, “We’ll stop if something comes up”. Start-work authority and stop-work authority should reinforce each other, not compete with each other.
Most serious incidents don’t start with one big dramatic failure. They start with rushed beginnings, missed checks, and unspoken assumptions. Start-work authority is how you break that pattern – by making the start of the job a conscious, supervised, and shared decision.
Because the safest work doesn’t just stop when it gets dangerous.
It starts when leaders and crews agree it’s truly ready.
