Should hours spent on training be considered hours worked?

It depends on the situation. Generally, voluntary training that takes place outside of usual working hours isn't considered working hours, whereas required work training or training that occurs during usual working hours are considered to be payable working hours.

FLSA hours worked advisor

The Fair Labor Standards Act sets [regulations regarding which training hours must be considered working hours.

The first deciding factor is if the training occurs during an employee's regular work hours.

If yes

The training is most likely considered work hours and must be paid, unless all of the following criteria are met:

• Attendance of the training is voluntary
• The course isn't directly related to an employee's position
• The employee doesn't perform any productive work for your company during the training

If no

The training isn't considered hours worked, provided that the training is voluntary. Training isn't voluntary if:

• You (as the employer) require it
• Your employee is led to believe that not attending the training will adversely affect their position in the company, or their working conditions
• Disciplinary action will be taken against employees for not attending

Conclusion

Time employees spend training for their positions is considered working time, and must be paid by employers. Exceptions include optional trainings that take place outside of normal working hours or aren't directly related to an employee's position.
