Mitigation in Employment Cases: How the Economist Measures It

By Christopher Skerritt, M.Ed., MBA, Chief of Economic Services · Published

Mitigation in an employment case is the principle that a terminated or demoted employee's damages are reduced by what the employee earned, or with reasonable effort could have earned, after the adverse action. Whether the employee's efforts were reasonable is a question for the trier of fact; what the interim earnings were, what comparable work paid, and how the answer changes the loss are questions for the economist. This guide explains which earnings are netted, how a lower-paying or self-employed replacement is handled, what the defense's failure-to-mitigate argument looks like in numbers, and how the report presents the loss under each version so counsel on either side can argue the facts.

What mitigation means in an employment claim

An employee who loses a job is expected to look for another one, and the damages for the lost job are measured net of what the search produced or should have produced. The principle divides into two questions that different people answer. Whether the employee made reasonable efforts, whether a particular position was comparable enough that turning it down was unreasonable, and who bears the burden of proving either point are legal questions for counsel and the trier of fact, and the answers differ by venue and by the statute the claim is brought under. What the employee actually earned after the termination, what the positions the parties point to actually paid, and what the loss is under each answer are economic questions, and the employment and wage loss damages analysis answers them without taking a side on the legal ones.

The economist's discipline is to keep the two apart on the page. The report never states that the employee mitigated or failed to; it states the interim earnings the records show, the earnings the alternative positions would have produced, and the back pay and front pay figures under each, so that whichever finding the trier of fact makes, the number that follows from it is already on the schedule. The mitigation and offsets method page describes the general mechanics; this guide concerns the employment setting, where the offset is usually the largest single deduction in the claim.

Which earnings are netted

The offset is earnings from replacement employment: the wages, bonuses, and benefits of the jobs the employee held after the termination, taken from the pay records and tax returns for each year of the loss period and matched year by year against the pay of the position lost. Earnings the employee would have had anyway, such as a second job held before the termination and continued afterward, are not an offset, because they do not replace the lost pay; the report identifies them and leaves them out. Earnings from a job the employee took only because the lost position was gone are the offset the principle contemplates, and they are deducted in full.

Some receipts are not earnings and are handled separately. Unemployment compensation, severance, and benefits paid under a plan are treated differently from venue to venue and statute to statute, and whether each reduces the award is a legal question the economist does not decide. The report lists each receipt on its own line with its dates and amounts so counsel can apply the rule that governs, and the collateral source guide explains why the answer is not the economist's to give.

Lower-paying and self-employed replacement work

A replacement job that pays less than the position lost does not end the claim; it reduces it. The loss in each year is the pay of the lost position less the pay of the replacement, and the gap may narrow as the employee gains seniority in the new job or widen as the raises the old position would have carried outpace the new one. The report projects both streams on their own growth paths, from the old employer's pay scale and the new employer's, and the difference is the continuing loss. A job that pays more than the lost position ends the loss in the year the crossover occurs, and the report shows the year.

An employee who went into business rather than back to work presents a harder measurement. The business's net income is the offset, but only after the owner's labor has been separated from the return on the money and equipment put into it, and only after start-up losses in the early years have been treated consistently with the rest of the schedule. The tax returns post describes how the business schedule is read; the report states whether the early losses were counted against the interim earnings and why.

The failure-to-mitigate argument in numbers

A defense that the employee did not look hard enough, or turned down comparable work, is an argument about what the interim earnings should have been rather than what they were. In most frameworks the employer carries the burden of showing that comparable positions were available and that the employee did not reasonably pursue them, and the argument arrives with evidence: postings, offers, or the wages of the occupation in the local labor market. The economist's task is to turn that evidence into an alternative interim earnings stream, from the wages the positions actually paid, and to compute the back pay and front pay that result. The report then shows the loss under the actual interim earnings and under the constructive ones, and the trier of fact chooses between them.

The constructive stream has a start date as well as a wage. An argument that comparable work was available is an argument about when the employee could have started it, and the loss between the termination and that date is unaffected by the argument. The report dates the constructive stream from the evidence, applies the wages the record supports, and grows it on the same terms as the actual one, so the only difference between the two schedules is the point in dispute.

Benefits during the gap

The lost position carried benefits, and the replacement job may carry fewer or none. Health coverage is the usual gap: an employee who paid for continuation coverage or bought a policy has a documented cost, and one who went without has lost a benefit whose value the employer's cost data establish. Retirement contributions the old employer would have made, and the vesting or accrual the termination interrupted, are a loss even where the replacement job has a plan of its own, because the two are netted, not ignored. The fringe benefits valuation page sets out how each benefit is priced; in the employment setting the point is that the benefit side of the lost position and the benefit side of the replacement are netted with the same care as the wages.

How the schedule presents it

The back pay schedule runs year by year from the termination to the date of trial, with the lost position's pay and benefits in one column, the interim earnings and benefits in the next, and the difference in the third, in the dollars of each year. The front pay schedule continues from the trial date over the period the record supports, with both streams projected and the difference discounted to present value, and the back pay versus front pay comparison explains the divide. Where the failure-to-mitigate argument is live, a second pair of schedules substitutes the constructive interim earnings, and a summary page shows the four totals side by side. Counsel in a New York wrongful termination matter, or in any venue, can then argue the legal question with the economic consequence of each answer already in evidence.

Opposing reports go wrong in predictable ways: an offset that includes earnings the employee would have had anyway, a replacement stream frozen at its starting wage while the lost position's stream grows, a constructive earnings figure with no start date, unemployment compensation deducted in a venue that does not allow it, and a benefit gap ignored because the replacement job had a plan. Each is visible on the schedule, and the rebuttal guide lists the questions that expose them.

Frequently Asked Questions

Are unemployment benefits deducted from an employment award?

That depends on the venue and the statute, and the economist does not decide it. The report lists the unemployment compensation received, with dates and amounts, on its own line, so counsel can apply the governing rule and the trier of fact can see the figure with and without the deduction.

Does a lower-paying replacement job end the back pay claim?

No. It reduces the loss to the difference between the two positions in each year. The report projects the lost position's pay and the replacement's pay on their own growth paths, and the loss continues until the replacement catches up, which the schedule shows as the crossover year, or until the period the framework allows has run.

What does the economist do with a claim that the employee stopped looking for work?

The economist builds a second interim earnings stream from the wages of the work the employer says was available, dated from when the evidence says it could have started, and computes the loss under that stream beside the loss under the actual earnings. Whether the employee's search was reasonable is left to the trier of fact.
