Capstone: a violence risk assessment and response plan for an invented store

This final lesson puts the course together. We follow Marco Delgado, Northfield's safety lead, as he helps the owner of Riverside Corner Market, the small convenience store we have met throughout the course, carry out a violence risk assessment and write a response plan. Riverside has no robbery history, but it has had thefts, two threatening incidents after refusals, and many of the risk factors from Lesson 3. The aim is a plan that is practical for a small store with a modest budget, that meets the legal requirements from Lesson 2, and that workers understand and support.

Riverside Corner Market

Riverside is an invented convenience store in Kamloops. It is open from 6 a.m. to midnight every day, sells groceries, snacks, tobacco, vaping products, lottery tickets and prepaid cards, and is next to a busy road with a side parking lot. It has eight part-time workers and the owner, Dana Lau, who works most day shifts. Evenings usually have two workers; mornings sometimes have one for the first hour. The store is not licensed to sell alcohol. Its late-night hours mean BC's late-night retail rules apply between 11 p.m. and midnight, which HSE-352 covers in detail; this plan addresses them only at a high level.

Step 1: gather information

Marco and Dana start with what the store already knows and what workers think. They review two years of incident notes, police reports for thefts, and the store's two threatening incidents. They walk the store and lot at opening, at 9 p.m. and at closing. They also ask every worker to complete a short, anonymous survey about how safe they feel at different times and tasks, using a five-point scale from strongly disagree (1) to strongly agree (5). The program below summarizes the responses.

# Summarize Riverside's anonymous staff safety survey (responses are invented; 1 = strongly disagree, 5 = strongly agree).
survey = {
    "I feel safe working the morning opening":         [4, 3, 2, 4, 3, 2, 3, 4],
    "I feel safe working the evening shift":            [3, 2, 3, 2, 2, 3, 2, 3],
    "I feel safe during closing and leaving":           [2, 1, 2, 2, 3, 1, 2, 2],
    "I know what to do in a robbery":                   [3, 2, 2, 3, 2, 4, 2, 3],
    "I can get help quickly if a customer is abusive":  [2, 3, 2, 2, 3, 2, 3, 2],
    "I would be supported if I refused a sale":         [4, 4, 5, 3, 4, 4, 5, 4],
    "Reporting an incident is quick and worthwhile":    [2, 2, 3, 2, 1, 2, 3, 2],
}
rows = []
for item, r in survey.items():
    mean = sum(r) / len(r)
    agree = sum(1 for x in r if x >= 4) / len(r)
    rows.append((mean, item, agree))
for mean, item, agree in sorted(rows):
    flag = "PRIORITY" if mean < 2.5 else ("watch" if mean < 3.5 else "ok")
    print(f"{mean:4.2f}  agree {agree:4.0%}  {flag:<8} {item}")

1.88  agree   0%  PRIORITY I feel safe during closing and leaving
2.12  agree   0%  PRIORITY Reporting an incident is quick and worthwhile
2.38  agree   0%  PRIORITY I can get help quickly if a customer is abusive
2.50  agree   0%  watch    I feel safe working the evening shift
2.62  agree  12%  watch    I know what to do in a robbery
3.12  agree  38%  watch    I feel safe working the morning opening
4.12  agree  88%  ok       I would be supported if I refused a sale

The survey results line up with the walk-throughs. Workers feel least safe during closing and leaving, do not think reporting is quick or worthwhile, are not confident they can get help quickly with an abusive customer, and are unsure what to do in a robbery. They do feel supported when refusing sales, which is a strength the owner has built by backing staff. The lowest scores become priorities for the plan.

Step 2: identify hazards and situations

From the information, Marco and Dana list the situations that could lead to harm. For each one they note when it happens, what controls already exist, and what could go wrong.

Step 3: assess the risk

For each situation, Marco and Dana rate likelihood and severity on a simple 1 to 5 scale and multiply them to get a risk score, first with the current controls and then with the planned controls. The ratings are judgments, informed by the incident history, the walk-throughs, the survey and the risk factor checklist from Lesson 3. The program below calculates the scores and ranks the situations.

# Risk matrix for Riverside: likelihood x severity (1 to 5 each), before and after planned controls.
# Ratings are the assessors' judgments, not measurements.
risks = {
    "Robbery at the counter":          ((2, 5), (1, 4)),
    "Aggression after refusal":        ((4, 3), (3, 2)),
    "Threats during theft":            ((3, 3), (2, 2)),
    "Opening alone":                   ((2, 4), (1, 3)),
    "Closing and leaving":             ((3, 4), (1, 3)),
    "Harassment of young workers":     ((3, 3), (2, 2)),
}
def band(s):
    return "HIGH" if s >= 12 else ("MEDIUM" if s >= 6 else "LOW")
print(f"{'Situation':<32} {'now':>5} {'band':<7} {'after':>6} {'band':<7}")
for name, ((l0, s0), (l1, s1)) in sorted(risks.items(), key=lambda kv: -kv[1][0][0] * kv[1][0][1]):
    a, b = l0 * s0, l1 * s1
    print(f"{name:<32} {a:5d} {band(a):<7} {b:6d} {band(b):<7}")
before = sum(l * s for (l, s), _ in risks.values()); after = sum(l * s for _, (l, s) in risks.values())
print(f"Total score: {before} now, {after} after controls ({100 * (before - after) / before:.0f}% lower)")

Situation                          now band     after band   
Aggression after refusal            12 HIGH         6 MEDIUM 
Closing and leaving                 12 HIGH         3 LOW    
Robbery at the counter              10 MEDIUM       4 LOW    
Threats during theft                 9 MEDIUM       4 LOW    
Harassment of young workers          9 MEDIUM       4 LOW    
Opening alone                        8 MEDIUM       3 LOW    
Total score: 60 now, 24 after controls (60% lower)

Two situations rank high with current controls: closing and leaving, and aggression after refusals. Robbery at the counter ranks medium because its likelihood is low, but it has the highest severity of any situation, which is why it still gets priority attention. With the planned controls, aggression after refusals drops to medium and every other situation to low, and the total score falls by 60%. The scores are rough, but they make the priorities clear and give a baseline for next year's review.

Step 4: choose controls

Following the hierarchy of controls from Lesson 2, Marco and Dana look first for ways to remove or reduce the hazard, then for design changes, then for procedures and training. They keep costs in mind; Riverside is a small business.

Several controls address more than one situation. Two workers on the floor in the evening reduce robbery risk, give backup during refusals and make closing safer. Clear windows help with robbery and with aggression, because people behave differently when they know they can be seen. That is typical: a small number of well-chosen controls usually covers most of the risk.

Step 5: write the response plan

Riverside's written plan is short, about four pages, so that workers will actually read it. It includes:

• The policy statement: violence, threats, harassment and abuse of staff are not accepted; workers are never expected to protect money or goods; workers will be supported when they refuse sales, step away or report.
• The risk assessment summary and the controls above, with owners and dates.
• Procedures for robbery (Lesson 6), aggressive customers and de-escalation (Lessons 7 and 8), refusals and suspected theft (Lesson 9), harassment, abusive calls and online abuse (Lesson 10), and opening, closing and cash handling (Lesson 5).
• Emergency contacts: 911, the owner's cell, the non-emergency police line, the EAP number and the 988 crisis line.
• Reporting and follow-up: the form, who to give it to, and the 1, 7 and 30-day check-ins (Lesson 11).
• Training: what new workers learn before their first shift, and the annual refresher.
• Review: the plan is reviewed every year and after any serious incident, with worker input.

Step 6: train, communicate and involve workers

Dana holds a short meeting with all workers to walk through the plan, explain why each change is being made, and ask for comments. The survey results are shared, and workers see that their concerns about closing and reporting are at the top of the list. New workers get the plan before their first shift and do a calm walk-through of robbery response and refusal scenarios with Dana. A worker representative is chosen to join the owner in incident investigations and the yearly review.

Step 7: measure and review

The plan includes a few simple measures, reviewed every three months:

• Leading: share of shifts with two workers on the floor after 8 p.m.; cash limit breaches; share of workers trained; days to follow up reports; survey scores repeated every six months.
• Lagging: incidents by type and rate per 10,000 transactions; injuries; thefts with threats.

Early in the plan, incident reports may rise because reporting has become easier. Dana and Marco expect this and treat it as a sign the program is working, not that the store has become more dangerous. Over time, they expect the share of serious incidents and the survey gaps to fall.

Looking ahead

This plan focuses on robbery, aggression and harassment. Two related areas are covered in other courses. HSE-352 covers working alone and late-night safety at convenience stores and fuel stations in depth, including the legal requirements for late-night staffing and barriers. HSE-342 covers the backroom: receiving, pallet jacks, racking, balers and compactors. Together with HSE-340, these courses cover the main hazards of retail work.

For supervisors: make the plan a habit

A plan that sits in a binder does nothing. Bring one part of it into each team huddle: the cash limit, the code phrase, the closing routine, how to report. Ask workers what is working and what is not. When something goes wrong, use the plan's follow-up steps and tell the team what changed. When something goes right, such as a worker handling an angry customer well or refusing a sale with backup, say so. Those small habits are what turn a written plan into a safer store.
