IBE Manufacturing Audit — Jackson County, IN: the 10 largest employers, reviewed
Jackson County’s 5,000+ manufacturing jobs are concentrated in roughly ten plants. They build the cars, electrical wiring, plastic packaging, pharmaceuticals, and steel tubing that pass through Seymour, Crothersville, and Brownstown every day. They are also the single biggest determinant of whether a working-age county resident has a stable wage, a benefits package, and a future. This IBE audit aggregates publicly available employer-review data (Indeed, Glassdoor, Facebook), maps the recurring complaints, and identifies which plants are working better — and which need scrutiny.
1. The top 10 manufacturing employers by headcount
Per 2024 Jackson County economic-development data, these are the largest manufacturers in the county:
2. The recurring complaints — what employees say across plants
Aisin USA (Seymour) — toxic-culture flags
- Favoritism & retaliation against employees who raise concerns.
- Mandatory 10-hour shifts six days/week with rare full weekends off.
- Upper-management indifference, low pay relative to demands, high turnover.
- PTO accrual: 5 vacation days year-one (4 tied to July-4 shutdown); rated “stingy” against 60-hr weeks.
Valeo North America (Seymour) — lowest-rated in set (2.8/5 Glassdoor)
- Bullying team-leaders and forced night-shifts post-trial period.
- Lowest starting wages despite multi-role demands; payment delays reported.
- Cutthroat environment where favoritism dictates overtime and advancement.
- PTO: 2–3 weeks immediate vesting, but reviews note conflicts with mandatory overtime.
Cerrowire LLC (Crothersville) — Indeed management 2.8/5
- Low management scores; safety-related concerns appear in employee comments.
- Smaller plant footprint; high-impact local-employer for the Crothersville-area workforce.
Silgan Plastics (Seymour) — ~3.0/5 Indeed
- Overtime stress and mid-range supervisor ratings.
- Mid-tier in the set on culture, but small enough that individual managers move the rating.
The brighter side — Aisin Drivetrain & RR Donnelley
- Aisin Drivetrain (Crothersville): Facebook 80% recommend (n=12). Smaller plant feel; higher peer-to-peer satisfaction.
- RR Donnelley (Seymour): Indeed 3.5/5 — highest in the set. Shift-stability and supervisor-quality cited positively.
3. The pattern across plants
Five themes recur in negative reviews across the lower-rated plants (Aisin USA, Valeo, Cerrowire, Silgan, Lannett):
- Mandatory overtime that becomes the norm rather than the exception. 60-hour weeks normalized; PTO becomes hard to use even when accrued.
- Favoritism in advancement and overtime allocation. Reviewers consistently describe a perception that the “right people” get the OT and the promotions.
- Retaliation against people who raise safety or culture concerns. Specifically named at Aisin USA; suggested at others.
- Pay below the cost of the demands. Operator pay $15–$24/hr region-wide, with mandatory OT pushing total compensation but increasing burnout.
- Turnover that masks the real issue. 30–38% annualized turnover at the lowest-rated plants vs. 25–30% at better-managed peers (Denso, Magna industry benchmarks).
4. Pay benchmarks across the local set
Operator hourly pay (2025–2026 estimates from Indeed / Glassdoor):
- Aisin USA: $15–$22/hr ($17.59 avg.) — trails the set on base; OT-driven total comp.
- Valeo: $18–$23/hr.
- Magna (regional benchmark): $20–$22/hr ($20.45 avg., ~$42.5K annual).
- Denso (regional benchmark): $19–$24/hr (estimated).
- Top Jackson County manufacturing: skilled positions $20–$27/hr; engineers/supervisors $44K–$62K annually.
5. Safety & injury rates — what we can verify
No plant-specific public injury data was located for any Jackson County manufacturer. The applicable benchmarks:
- Indiana manufacturing 2024: 2.7 nonfatal incidents per 100 full-time workers — a record low (was 2.6 in 2023, 3.6 prior years), per BLS.
- National manufacturing: 3.2 per 100 FTE for nonfatal injuries / illnesses.
- Automotive supplier sector contributed to declines via ergonomic and safety programs.
Counties without published plant-level safety data are functionally invisible to the public on this metric — even residents whose family members work there. We flag this as a transparency gap, not as a verdict on any specific operator.
6. PTO & benefits comparison (regional set)
- Denso (regional benchmark): most generous PTO — flexible accrual + 13 paid holidays; cash-out options. Reviews praise structure.
- Magna: 15–20 vacation days for full-time; 20–30 days at 10+ years tenure. Reviews note approval inconsistency under production demands.
- Valeo: 2–3 weeks immediate vesting — quick access, but scheduling conflicts under mandatory OT.
- Aisin USA: 5 vacation days year-one (4 tied to plant shutdown); slow accrual rate per Glassdoor.
7. The IBE verdict — how to read this audit
Highest concern (warrants county-level scrutiny)
- Valeo North America (2.8/5 Glassdoor) — consistent reports of bullying, lowest pay, retaliation against shift-protests.
- Aisin USA — the volume and consistency of culture complaints relative to plant size (2,195 employees) makes individual variance unlikely; pattern suggests systemic issues.
- Cerrowire (Crothersville) — smaller plant, but management 2.8/5 in a company that anchors a town economy.
Performing as expected (mid-tier)
- Cummins Seymour Engine Plant, Lannett, Silgan Plastics, The Royal Group — ratings cluster around 3.0–3.2/5 with no recurring red-flag patterns.
Better-than-set (positive signals)
- Aisin Drivetrain (Crothersville) — 80% Facebook recommend; smaller plant culture appears to outperform the larger Aisin USA Seymour location.
- RR Donnelley (Seymour) — 3.5/5 Indeed, highest in the set; shift-stability cited as positive.
8. What residents and prospective hires can actually do
- Read recent reviews, not aggregate ratings. A 3.0/5 on Indeed today might be 4.0 from 2018 dragged down by 2.0s from the last year. Open the “recent first” sort.
- Talk to current employees, not just former. Departure reviews skew negative; current-employee comments (sometimes filtered) tell you what the day-to-day is like.
- Ask in the interview about overtime expectations. “Mandatory” vs. “voluntary” OT is the single biggest predictor of burnout. The answer should be specific.
- Compare benefits in writing. PTO accrual rate, holiday count, healthcare premium, 401(k) match, attendance-policy details. Get them on paper before you accept.
- Use Indiana DOL+OSHA references. If you witness a credible safety violation or retaliation, the Indiana Department of Labor and federal OSHA accept anonymous-OK complaints. Document with dates.
9. What county economic-development staff and elected officials can do
- Tie tax-incentive renewals to documented retention metrics. A plant claiming workforce-investment dollars while turning over 35% of its workforce annually is a documentable mismatch.
- Publish anonymized BLS injury rates by plant where you can. Other Indiana counties (e.g., Bartholomew with Cummins) demonstrate this is possible without exposing individuals.
- Coordinate with the Jackson County Health Department and Indiana DOL on plant-level investigation when employee-review patterns are systemic across years.
- Use the IBE submission form to forward documented complaints (timecards, written communication, written disciplinary actions) for further public-record investigation.
10. The bottom line
Jackson County’s manufacturing base is the foundation of the local economy — but the labor-side reviews tell a more uneven story than the headline employment numbers. The plants where workers consistently feel treated as adults (Aisin Drivetrain Crothersville, RR Donnelley) outperform the larger flagships (Aisin USA Seymour, Valeo) on retention, advancement, and culture. The transparency gap on safety and on retaliation handling is the single biggest unfilled piece — and the easiest one for the county to begin closing without a single dollar of new spending.
Sourcing standard: this audit aggregates publicly visible employer-review data from Indeed, Glassdoor, and Facebook as of April 2026. Specific complaints are paraphrased from public posts.
