One row = one FLSA workweek. Overtime hours are the hours past 40 in that week. A bonus that covers several weeks has to be split across the weeks it was earned in (29 CFR 778.209).

Why this matters

Nondiscretionary bonuses must be included in the regular rate before calculating OT. Failing to do so is one of the most common FLSA violations — and DOL can collect 2–3 years of back wages plus liquidated damages equal to the back pay.

Nondiscretionary vs. Discretionary

Include: Production bonuses, commission, shift differentials, attendance bonuses, on-call pay.

Exclude: Purely discretionary gifts, overtime premiums, vacation/holiday pay.

FWW caution

Fluctuating workweek is legally available but risky. Bonuses and other extra pay are allowed, but they must go into the regular rate (29 CFR 778.114(a)). The salary has to be fixed, cover all hours, and be enough to meet minimum wage in your longest week (29 CFR 778.114(a)). If the employee's hours aren't genuinely fluctuating, it doesn't apply.
