Some salaried workers get half time for overtime instead of time and a half, and it can be completely legal. Here is the rule behind it, the four conditions that must all hold, and the math worked through twice.

The fluctuating workweek method lets employers pay salaried nonexempt workers overtime at half the regular rate, because the salary already covers straight time for every hour. Each week the regular rate equals salary divided by hours worked, and each hour over 40 earns an extra half rate. Legal only when hours fluctuate, the salary never varies, and both sides agree.
Normal overtime math gives you time and a half: the regular rate plus an equal half. Under the fluctuating workweek method, you get only the extra half. The reasoning is that a fixed salary already pays you straight time for every hour you worked, including the overtime hours, so the employer only owes the missing premium. The regulation, 29 CFR 778.114, has worked this way since 1950, and a 2020 Department of Labor rule (the "bonus rule") confirmed that bonuses can sit on top of the salary without breaking the method.
The difference is large. A salaried worker on the standard method who works 50 hours at a $960 weekly salary gets an extra $240 in overtime. Under the fluctuating workweek method the same week pays $80 extra. Both are lawful, but only when every condition below is met. If even one fails, the worker is owed standard time and a half.
You earn a fixed salary of $960 per week and work 48 hours.
Notice the salary already covered $20 for each of those 8 overtime hours at straight time. The $80 is only the missing half. The same 48 hour week at a flat $20 hourly wage would cost $1,040 too, which is a useful sanity check on the math.
You earn a fixed salary of $800 per week, work 50 hours, and earn a $100 nondiscretionary attendance bonus that week.
Under the 2020 rule, the bonus is compatible with the method but must be folded into the regular rate. Without the bonus the premium would have been $80; the bonus pushed it to $90. An employer that ignores the bonus and pays $80 has underpaid.
Pay rules on this page follow DOL Fact Sheet 82: Fluctuating Workweek Method of Computing Overtime and the regulation at 29 CFR 778.114.
Only under the fluctuating workweek method, and only if you are a nonexempt salaried employee whose hours vary week to week, whose salary never changes, and who has a clear mutual understanding with the employer that the salary covers all hours worked. Every one of these conditions must hold.
Yes. That is the core bargain of the fluctuating workweek method. If your employer docks your salary when you work fewer hours, the fixed salary requirement fails and the method cannot be used for that week.
Yes. Since the 2020 bonus rule, bonuses, commissions, and other incentive pay can be paid on top of the fixed salary under the fluctuating workweek method, but they must be included when computing the regular rate.
No, according to the Department of Labor. Hours must vary from week to week, but the Department's position is that they do not have to fall below 40. Some courts have disagreed, which is one reason to get local advice on disputed cases.
No. A clear mutual understanding that the fixed salary covers all hours worked is a legal requirement. If you never agreed to the arrangement, the employer owes you standard overtime at time and a half.
