The Washington state leave sharing program as established in RCW 41.04.650 through 41.04.670 provides that employees may donate annual, sick, and personal holiday leave to other employees for sick leave purposes. The purpose of the shared leave program is to permit state employees to aid fellow state employees who are suffering from, or have a relative or household member suffering from, extraordinary or severe illness, injury, impairment, or physical or mental condition which have caused or are likely to cause the employees to take leave without pay or terminate their employment.
