Bellweather Distributing: A Turnover Problem and a $92,000 Structural Fix
Bellweather Distributing employs 120 people, 78 of them warehouse associates across two shifts. Voluntary turnover in the warehouse ran 38% last year (34 departures) against a regional benchmark of 22%. In exit interviews, 21 of the 34 departing associates named my supervisor as a reason; the day-shift supervisor carries 22 direct reports and has had no management training. Fully loaded replacement cost per associate - recruiting, onboarding, and lost productivity - is estimated at $4,800. Absenteeism runs at 6.1% against a 3.5% benchmark. HR proposes two new team leads at $46,000 each including benefits, a total of $92,000 a year. The plant manager prefers a $6,500 leadership course for the supervisor plus a $2.00 per hour differential for four senior associates who would each take a team of about 10. The owner wants a decision before the next budget cycle.
1. Compute the annual hard-dollar savings from reducing turnover to the regional benchmark, and the turnover rate at which the HR proposal breaks even. What does the result imply about how the decision must be argued?

- Departures avoided: moving from 38% to 22% on 78 associates is 16 points × 78 = 12.5 hires avoided per year. At $4,800 each = about $60,000 in hard savings.
- Cost: $92,000. Net: −$32,000. On hard replacement dollars alone, the proposal does not pay.
- Break-even turnover: $92,000 ÷ $4,800 = 19.2 hires avoided, a 24.6-point drop. Turnover would have to fall to about 13.4% - better than the regional benchmark.
Implication. The case cannot be won on replacement cost alone, so a simple cost-benefit verdict would kill a fix that may still be correct. Either the intervention must be cheaper, or the benefit must include costs not captured in the $4,800 - 6.1% absenteeism, overtime, rework and safety incidents, and the supervisor's own turnover risk. The honest conclusion is that the $4,800 figure is doing too much work and should be rebuilt before the proposal is judged.
2. The plant manager says the numbers do not work, so nothing should change. Evaluate that conclusion and recommend a course of action.

The conclusion is premature, though the arithmetic is honest. Three gaps:
- The $4,800 probably understates cost. It usually excludes overtime, temporary labor, quality errors, and the drag a 22-report span puts on everyone. If the true cost is $7,000, savings rise to about $87,500 and break-even turnover falls to roughly 25%.
- The counter-proposal is cheaper, not proven. $6,500 plus four $2.00/hour differentials (about $16,600 a year with payroll taxes) totals roughly $23,000 - a strong argument for piloting it, not for assuming it works. A course alone rarely fixes a 22-report span; the structural change is what reduces span of control.
- The cause is specific, and so the fix should be. Twenty-one of 34 exits naming the supervisor points to supervision, not associate pay. The intervention should change that supervisor's span and behavior.
Recommendation. Run a six-month pilot on the day shift: one team lead, a coaching program for the supervisor, and a span near 12 reports. Compare turnover and absenteeism against the untouched night shift before budgeting the full $92,000. Staging converts an argument about forecasts into an argument about observed results.
3. Design the six-month pilot: participants, measures, success criteria, and how you would isolate the effect of the change from seasonal and market factors.

Design. The day shift (about 40 associates) receives the intervention; the night shift (about 38) continues as a comparison group, so both experience the same season, labor market, and hiring standards.
Intervention: one team lead at about $46,000 annualized ($23,000 for six months), span reduced from 22 to roughly 12, and a structured coaching program for the supervisor with monthly observation and feedback.
Baseline: day-shift turnover and absenteeism for the prior 12 months, pulled by shift rather than warehouse-wide.
Success criteria, set before launch:
- 90-day new-hire retention improves by at least 10 points over baseline.
- Voluntary separations fall at least 25% relative to the comparison shift.
- Absenteeism moves from 6.1% toward 4.5%.
- Exit-interview mentions of supervision fall by half.
Controls and guardrails. Exclude seasonal layoffs from the turnover count; note any regional wage change that affects both shifts; and check that the night shift does not deteriorate - if it does, the team lead may simply be pulling talent from the other shift.
Decision point: at month six, fund the second team lead if two of the four criteria are met; if not, stop and address span through scheduling instead.
