ANYTHING under 40 hours.

It really depends on the "employer". My personal experience 15-24 hours per week.

How many hours per day or per week can an employee work?

The FLSA does not limit the number of hours per day or per week that employees aged 16 years and older can be required to work.

How many hours is full-time employment? How many hours is part-time employment?

The FLSA does not define full-time employment or part-time employment. This is a matter generally to be determined by the employer. Whether an employee is considered full-time or part-time does not change the application of the FLSA.

When can an employee’s scheduled hours of work be changed?

The FLSA has no provisions regarding the scheduling of employees, with the exception of certain child labor provisions. Therefore, an employer may change an employee's work hours without giving prior notice or obtaining the employee's consent (unless otherwise subject to a prior agreement between the employer and employee or the employee's representative).
