Time Tracking and Paycheck Accuracy

The Department of Labor estimates that wage theft (unpaid wages, off-the-clock work, misclassified overtime) affects millions of US workers annually. Keeping your own time records and verifying your paychecks against hours worked is a basic protection.

The Biweekly Paycheck Math

Most US employers pay biweekly (26 pay periods/year). A $25/hour worker working exactly 40 hours/week: $25 × 80 hours = $2,000 gross per biweekly paycheck. After taxes (roughly 25%–30% for federal + state + FICA): approximately $1,400–$1,500 net. Two months per year have 3 paychecks instead of 2 — useful for budgeting.

Exempt vs. Non-Exempt Classification

Misclassification as “exempt” (and therefore ineligible for overtime) is a common wage violation. To be legitimately exempt under FLSA: you must earn above $684/week ($35,568/year) AND meet a duties test (executive, administrative, professional, outside sales, or computer roles as defined by DOL). Job title alone doesn’t determine exemption — the actual work performed determines it. If you’re classified as exempt but don’t meet the duties test, you may be owed back overtime pay.
