Northfield Precision Plastics, the survey figures and all pay rates are composites written for a model paper; methods, legal points and research findings come from the sources listed and are stated generally.

Week 1 gave Northfield Precision Plastics, the composite Minnesota injection molding company, a point score for each of its 40 jobs and a policy to lead the market for critical technical jobs and match it for others. The points rank the jobs; they do not say what to pay. A pay structure is where internal worth meets the outside market, and building it means translating points into dollars without losing either. This paper builds that structure.

Choosing Surveys

Northfield uses two salary surveys: a regional survey of Minnesota manufacturers with more than 200 respondents and a national survey of plastics processors that includes process technicians and tooling roles. Using two sources reduces the risk that one survey's sample distorts the picture. The HR manager checked each survey's methods, the number of companies reporting each job and the date of the data (Milkovich et al., 2020).

Matching Benchmark Jobs

Benchmark jobs are those found in many companies with similar duties, so survey data can be matched reliably. Northfield chose 14 benchmarks, including machine operator, quality inspector, maintenance mechanic, process technician, quality engineer and production supervisor. Matching is done by comparing the survey's job description with Northfield's, not by title alone. Northfield's process technicians validate processes for medical customers, a step above the survey's general process technician, so the HR manager used the survey's senior level for that match.

Aging the Data

The regional survey reflects pay as of January, the national survey as of the previous July. Northfield's structure will take effect next January. Using expected wage growth of 3.5 percent a year, January data are aged forward 12 months and July data 18 months, about 5.3 percent, so all figures reflect the same date.

Fitting the Market Line

Plotting market median pay for the benchmarks against their job evaluation points shows a clear upward relationship. A simple regression gives a market line of roughly $12.40 an hour plus 3.2 cents per point. A job with 300 points has a market rate of about $22.00 an hour, and a job with 700 points about $34.80. Jobs that are not benchmarks are priced from the line using their points, which keeps them consistent with their internal worth.

Applying the Pay Policy

For technical job families where Northfield leads the market, the policy line sits 7 percent above the market line. For production and administrative jobs, it matches the market line. The policy line sets the midpoint of each grade.

Building Grades

Jobs with similar points are grouped into grades so that pay administration is manageable. Northfield's structure has eight grades for hourly jobs, each spanning about 75 points. Grade 2 includes material handlers and machine operators at 260 to 335 points; grade 6 includes process technicians and maintenance mechanics at 560 to 635 points.

Setting Ranges

Each grade has a range around its midpoint. Production grades have a range spread of 30 percent, minimum to maximum, because the skills in those jobs are learned fairly quickly. Technical grades have spreads of 40 percent, reflecting years of growth in skill. For grade 6, with a policy midpoint of about $33.70, the range runs from about $28.10 to $39.35. Adjacent grades overlap so that an experienced employee in one grade can earn more than a new employee in the next.

Compa-Ratios

Comparing each employee's pay with the midpoint gives a compa-ratio. Northfield's process technicians average a compa-ratio of 0.88, confirming the external problem found in Week 1. Eleven employees across several jobs are below their range minimum, and four are above their maximum. Research shows that pay comparisons matter to employees: Card et al. (2012) found that employees who learned they were paid below the median of their unit reported lower job satisfaction and were more likely to look for another job.

Bringing Employees Into Range

Raising the eleven employees below minimum to their range minimums costs about $96,000 a year. Raising process technicians toward the new midpoint over two years adds about $180,000 a year. The four employees above maximum are red-circled: their pay is not cut, but they receive lump-sum payments rather than base increases until the range moves up to them.

Minnesota's Posting Rule

Minnesota now requires employers with 30 or more employees to include a good-faith pay range or fixed wage in job postings. Northfield's grades provide that range directly, which simplifies compliance and gives candidates realistic expectations. Posted ranges also make pay structures visible to current employees, which raises the importance of internal equity.

Geographic and Shift Differentials

Northfield runs three shifts, and night work is harder to staff. Rather than building shift pay into the ranges, the company pays a differential of $1.50 an hour for second shift and $2.25 for third, so the structure stays clean and the premium is visible. Because its plant is in a smaller city, the company also compared regional survey data for the Twin Cities with data for southern Minnesota and found pay about 6 percent lower outside the metro area, which supports using the regional cut of the survey rather than the statewide average.

Pay Transparency and Trust

Rynes et al. (2004) noted that people often understate how much pay matters to them in surveys while acting strongly on it in their choices. Publishing ranges and explaining how they were set can build trust, but only if the structure is defensible, which is why the job evaluation and market matching must be documented.

Annual Updates

The structure will be updated each year by aging survey data and adjusting ranges, typically by a structure increase smaller than the merit budget, so that employees move through their ranges over time.

Conclusion

Two surveys, careful benchmark matching, aging to a common date and a market line relating points to pay turn Northfield's job evaluation into a pay structure of eight grades with ranges suited to each job family. Compa-ratios reveal underpaid technicians and a handful of employees outside their ranges, and the cost of corrections, about $276,000 a year, is the price of a structure the company can defend and post.
