Which type of contract indicates that an employee is paid based on the number of hours they work?

The type of contract that indicates an employee is paid based on the number of hours they work is typically the non-exempt workers contract. This type of contract is established under labor laws to protect employees who earn hourly wages and are entitled to overtime pay if they work beyond a set number of hours (usually 40 hours per week in the United States).

Non-exempt employees must be compensated for every hour worked, and their pay is calculated based on the actual hours worked, which aligns with the question's description. This structure benefits employees by ensuring they are fairly compensated for their time, especially when working extra hours.

The other options do not necessarily focus on hourly wages tied to hours worked. For example, temporary workers may be hired for a limited period but are not inherently paid based on hours worked unless specified in their contract; similarly, freelance contracts typically involve compensation for specific projects rather than hourly work. Commission-based roles, on the other hand, pay employees based on sales or performance metrics rather than the number of hours worked. This differentiation is crucial in understanding why the non-exempt workers contract is the most fitting answer.
