Number of paid hours worked by part-time employees of the organization during the reporting period.
Organizations should footnote all assumptions used.
This metric is intended to capture the number of hours worked by part-time employees over the course of the reporting period.
Organizations should exclude from this metric the number of hours worked by temporary employees—for these hours, organizations should report on Temporary Employee Hours Worked (OI8408).
Organizations are encouraged to report this metric in conjunction with Part-time Employees: Total (OI8864).
Metrics identified as "cross-category" are those that are relevant to any IRIS+ Impact Category or Impact Theme (i.e., these metrics are not specific to any particular industry/category or theme).

IRIS Metrics Work Better in Sets
To use IRIS metrics—and the resulting data—to understand impact performance, IRIS metrics should be used and analyzed in generally accepted sets and according to well-defined objectives. IRIS+ gives you access to generally accepted Core Metrics Sets aligned to common Impact Themes and Sustainable Development Goals (SDGs).
