There are some special situations where the time spent in attending
lectures, training sessions and courses of instruction is not regarded
as hours worked. For example, an employer may establish for the benefit
of his employees a program of instruction which corresponds to courses
offered by independent bona fide institutions of learning. Voluntary
attendance by an employee at such courses outside of working hours would
not be hours worked even if they are directly related to his job, or
paid for by the employer.
