I have a situation where an employer has three classifications of employees: full-time,40 p/wk.; part-time, 30 or < p/wk.; and as-needed.

Question: In determining the most recent one-year period of service for part-time employees, should the standard work-period be 1,560 hours (bi-weekly pay periods)per year? If so, should the years of service for each employee working less than 1,560 be some fraction of this number or, should the fraction be converted into the number of weeks of months? Further, should the includible compensation for each part-time employee consider as many years prior as needed to make up 1,560 hours?
How would this affect employees that move from a part-time to as needed position when the document does not exclude employees working less than 20 hours per week?
