Overtime, and who is exempt from it

Overtime, and who is exempt from it. What is actually the case, and how it compares with what is repeated.

For a practical software perspective on this topic, Monitask's practical guide provides a concise companion guide.

The forty-hour week is not a limit on how long anybody may work. In most places it is a threshold above which a premium becomes payable, and only for the workers the rule covers.

Covered and exempt

United States federal law requires time and a half beyond forty hours in a week for covered employees, and then defines categories of exempt employee to which it does not apply: broadly executive, administrative and professional roles, certain computer roles, and outside sales, each with its own duties test and most with a salary floor.

The salary floor has been revised, litigated and revised again. Where it sits determines how many people are covered, and it is one of the more consequential numbers in American employment law.

Salaried does not mean exempt

The commonest misunderstanding in this area, held by employers and employees alike. Being paid a salary rather than an hourly rate does not by itself remove the entitlement; the duties test has to be satisfied as well.

Misclassification is accordingly common, and it is generally discovered late, in bulk, and after somebody has left.

The European arrangement is different in kind

Rather than a premium above a threshold, the working time framework sets an average maximum, calculated over a reference period, together with minimum daily and weekly rest. It is a health and safety measure rather than a wage measure, which is why its structure differs.

Some member states have permitted individual opt-outs from the maximum. Whether an opt-out is genuinely individual when the alternative is not being hired is the argument that has followed it.

Why employers use overtime rather than hiring

Because a share of the cost of an employee is fixed rather than hourly: recruitment, training, equipment, and in some systems a substantial part of benefits. Paying an existing worker a premium for extra hours can be cheaper than paying an additional worker's fixed costs.

Which is why persistent overtime and unfilled vacancies coexist so often, and why an overtime premium set too low produces exactly this result.

Unpaid overtime, which is not a violation

For exempt staff, hours beyond the nominal week are not compensable and not counted. They are the design of the arrangement rather than a failure of it.

They are also badly measured, because the person doing them often does not count them either. Survey estimates of usual hours understate actual hours for salaried staff, and the gap is largest in the occupations where the culture treats long hours as evidence of commitment.

Time off in lieu

Compensating extra hours with later time off rather than with money. Where it is permitted it depends on rules about when the time may be taken and what happens if it never is.

The practical failure is the same everywhere: accrued time that cannot be taken because the workload that generated it has not gone away. A balance that only grows is a wage cut recorded as a benefit.

What to check about any overtime arrangement

Whether the role is covered or exempt, and on what basis. What the reference period is, if there is one. Whether the premium applies weekly or daily, since some jurisdictions require both. And whether time off in lieu, if offered, has an expiry.

These differ by country and by state, they change, and nothing here is legal advice. The point is which questions to ask rather than what the answers are.

The structural observation

Overtime rules are one of the few places where employment law puts a price on an employer's decision rather than prohibiting it. Set the price correctly and hours fall; set it too low and it becomes a cheap way of buying capacity.

Which makes the level of the premium and the width of the exemptions more consequential than the headline threshold, and they are the parts least discussed.

The threshold that decides the coverage

Because exemption generally requires both a duties test and a salary above a floor, the level of that floor determines how many workers are covered. Raising it brings in people who were exempt; leaving it unchanged while wages rise takes people out by inflation alone.

That second mechanism operates silently and it has removed coverage from large numbers of workers over long periods without any decision being taken.

A daily threshold as well as a weekly one

Some jurisdictions require a premium beyond a number of hours in a single day as well as beyond a weekly total. That matters for compressed schedules, where four ten-hour days may attract daily overtime while staying within the weekly limit, and it is a common trap in designing one.
