This is textbook misclassification. Under the FLSA, the "executive exemption" requires:
- Salary of at least $844/week (as of 2024 DOL rule)
- Primary duty is MANAGING the enterprise or a department
- Customarily and regularly directs the work of TWO OR MORE full-time employees
- Authority to hire/fire or recommendations carry particular weight
You fail criteria 2 and 3: if 90% of your time is non-managerial work and you only supervise one part-timer, you're almost certainly non-exempt and owed overtime at 1.5x your regular rate.
Damages: 6 months × ~12 overtime hours/week × 1.5x rate. Plus liquidated damages (double the unpaid wages under FLSA) if the employer can't prove good faith. Plus attorney fees.
Most wage theft attorneys work on contingency. The "Assistant Manager" title trick is one of the most common FLSA violations — you have a strong case. File a DOL complaint or contact an employment attorney. The statute of limitations is 2 years (3 for willful violations).
