Who is entitled to overtime in Iowa?
Iowa uses the federal salary threshold of $684 a week ($35,568 a year) plus the duties test. Employees below that salary, or without genuine executive, administrative or professional duties, are non-exempt and owed overtime for every hour above the threshold.
Misclassification is most commonly challenged in retail supervision, hospitality, home care and construction crews paid per job rather than per hour.
