Unpaid Leave of Absence

[Locust]

I wwork with old documents that say that hours of service will be credited for an unpaid leave of absence, provided that the company's leave of absence policy is administered in a nondiscriminatory manner. This would apply to all unpaid leave of absence, not just maternity/paternity.

Is this allowable?

Also, some of the plans say that hours are credited only in the year in which the unpaid leave of absence begins. And some say that the hours are credited only if the employee returns to work at the end of the leave.

Does any of this make sense?
