The Safety Shortcut on a Night Shift
You supervise a warehouse shift of 14 people. A conveyor guard was removed two weeks ago for a repair and has not been refitted because the replacement part is on backorder. Production has continued because the line runs 'fine' without it, and the shift has hit 104% of its pick target. Last night a new starter, three weeks in, caught his sleeve near the exposed rollers; he was not injured but is shaken and has told a colleague he 'doesn't want to make a fuss'. The maintenance manager says the part arrives in five days and asks you to 'keep it running quietly'. Your site manager is on leave and the next level of authority is the regional operations director, whom you have met twice.
1. What do you do in the next hour, and why?

Stop the line and make the exposure safe or shut it down.
Reasoning:
- Duty is non-delegable. As supervisor you have a personal legal duty to protect people from serious harm. A near-miss with exposed moving machinery is a foreseeable route to serious injury or death.
- Hierarchy of control: You cannot eliminate the hazard without the part, so the immediate step is to isolate the line or physically barricade and lock off the exposed section, and re-brief everyone on the shift.
- Record it. Log the near-miss, the removal date, the backorder, and the action you took. This protects the new starter, the shift and you.
- Escalate now, not later. The site manager's absence does not suspend the duty. Notify the regional operations director the same day, in writing, with the facts and the options (run at reduced speed with guarding, run a different line, or stop).
Accepting 'keep it running quietly' would make you complicit in a known, unmitigated risk.
2. The maintenance manager is more senior than you and the new starter does not want to complain. How do you manage both relationships?
Read the worked answer
Separate the two issues: the safety decision is not negotiable; the relationship management is.
With the maintenance manager:
- Be factual, not accusatory: state the exposure, the near-miss, and that you have isolated the line. Frame the escalation as protecting him as well as the shift.
- Offer to co-sign the escalation so it is a shared operational decision, not a complaint about him.
- Do not agree to a private 'quiet' arrangement. If pressed, say clearly that you cannot carry that risk and that the decision now sits with the regional director.
With the new starter:
- Thank him for reporting, reassure him that he is not in trouble, and explain what has changed as a result.
- Do not pressure him to make a formal statement, but record what he told you and offer him the safety representative or an independent route if he wants one.
Principle: a supervisor who trades a known risk for a quiet shift has chosen short-term peace over the safety of people who cannot protect themselves. The relationship cost of escalating is real but recoverable; an injury is not.
