Yes. In Massachusetts, an employee who does office work and nothing else should be rated in the clerical class, one of the lowest workers comp rates, while field employees are rated at their trade's much higher rate. The catch is that the Massachusetts rule is strict. Office work only, behind a real wall. One other duty, even a weekly parts run, puts that person's whole salary back at the field rate. Who this is for: Massachusetts contractors whose bookkeeper, office manager, or dispatcher shows up on the policy at the same rate as the crew.
The short version
- Office-only staff belong in the clerical class. A field rate on office payroll is one of the most common overcharges in Massachusetts.
- The Massachusetts rule is all or nothing. Office work only, behind a structural partition, or the whole payroll goes to the highest-rated field class.
- Clerical payroll cannot be split with a field class. It is all or nothing.
- A foreman or superintendent is rated for the work they supervise, not for the hours they spend at a desk.
- The fix is usually a wall, a job description, and a call to your broker before the audit.
Why should my office manager cost less to insure than my crew?
Workers comp is priced per $100 of payroll, at a rate for each class code (the job category the payroll is rated under). Massachusetts rates are approved by the state and are the same at every insurer. A carpenter's rate is many times the clerical rate because carpenters get hurt more often. The figures below are national illustrative ranges, not Massachusetts rates. They show the size of the gap, not a price.
| Employee | Class | National illustrative premium on $50,000 of payroll |
|---|---|---|
| Bookkeeper in a separate office | Clerical, code 8810 | $100 to $300 |
| Carpenter | Carpentry trade class | $2,500 to $5,000 |
| Roofer | Roofing trade class | $6,000 to $12,000 |
If your office manager earns $50,000 and is rated as a carpenter, you are paying far more than the rules require. See what a workers comp class code is.
Who qualifies for the clerical class in Massachusetts?
The Massachusetts workers comp manual, published by the state rating bureau, sets the test. Every part of it must be met.
| Test | What it means for you |
|---|---|
| Office work exclusively | Bookkeeping, record keeping, correspondence, or other office work. Nothing else, ever. |
| Physically separated space | The office must be separated from your shop, yard, or warehouse by structural partitions. A desk in the corner of the shop does not qualify. |
| Only clerical work happens there | If tools are staged or parts are sorted in the same room, the room is not a clerical office. |
| No other duty | An employee with any other duty has their total payroll assigned to the highest-rated class they are exposed to. Delivering a part to a job site counts. |
| No splitting | Clerical payroll cannot be divided with any other class, even with perfect time records. |
One thing not to worry about. If your policy's main category says it covers all employees, your office staff can still be rated separately. Massachusetts treats office work as its own category no matter what the main one says.
What about my estimator, project manager, or foreman?
The Massachusetts manual does not use the words estimator or project manager. Those employees are rated on what they actually do. An estimator who never leaves a partitioned office is clerical. One who walks job sites to measure is not. A foreman or superintendent is rated for the work they supervise. Downtime between jobs only counts as office work if they are truly at a desk or truly idle. If a supervisor already qualifies for the construction executive category, their office hours stay there too. See the national guide on whether a project manager or estimator can be classified as clerical.
How do I fix a misclassified office employee?
- Write down what each office employee actually does. Every duty, including errands.
- Look at the room. If there is no structural partition between the office and operations, build one. A stud wall and a door is often enough. Ask your broker to confirm before you build.
- Remove the field duties. If the office manager also runs parts, give that task to a field employee. Otherwise her whole salary stays in the field class.
- Ask your broker for a classification review. The insurer can correct the class mid-term, and the year-end premium audit (the insurer's check of your real payroll) will confirm it.
- Keep the records. Construction payroll can be divided between field classes only when your original records show each employee's actual time by task. Clerical cannot be divided at all.

What this looks like in real life
Illustrative example. It is typical of what we see and is not a promise of how any specific situation would be handled.
The setup: A plumbing company in Somerville has seven field plumbers, an office manager, and a dispatcher. The office manager and dispatcher share a desk area at the front of the open shop. Their combined payroll is about $105,000, all rated in the plumbing class.
What went wrong: Neither qualifies for the clerical class. There is no partition, and the dispatcher also drives parts to job sites twice a week.
What it cost: Illustrative numbers: a partition wall and door cost about $3,000. The office manager, who never leaves the office, moves to the clerical class and saves about $3,900 a year. The dispatcher stays in the plumbing class until his parts runs are handed to a field plumber, which saves another $2,800 the following year.
The fix: The wall paid for itself in less than a year. The bigger lesson was the dispatcher: in Massachusetts one field duty keeps a whole salary at the field rate, so job descriptions matter as much as the floor plan.
Frequently asked questions
Q: Should office staff cost less to insure than field employees in Massachusetts?
Yes. Office-only employees belong in the clerical class, one of the lowest workers comp rates, while field employees are rated at their trade's rate. The clerical class applies only to employees who do office work exclusively in space separated from operations by structural partitions.
Q: What counts as a structural partition in Massachusetts?
A real wall that separates the office from the shop, yard, or warehouse. A cubicle divider, a counter, or a desk in the corner of the shop does not qualify. Ask your broker to confirm before you rely on it.
Q: Can I split my office manager's payroll between clerical and field?
No. In Massachusetts, clerical and outside sales payroll cannot be divided with any other class. If she has any field duty, her entire payroll is rated in the highest-rated class she is exposed to.
Q: Is my estimator clerical in Massachusetts?
Only if the estimator works exclusively in a partitioned office. Visiting job sites to measure puts the whole payroll in a field class.
Q: What if I build the wall halfway through the policy year?
Ask your broker to have the class corrected from the date the office actually qualifies. Keep the dated invoice for the work so the year-end audit has proof.
Q: How do I get a misclassified employee corrected?
Ask your broker for a classification review with a written job description and a description of the office space. The insurer can correct the class mid-term, and the change is confirmed at the year-end premium audit.
