I think they see the use of sick leave expanding with more states allowing family sick leave. This is a huge benefit for households that have children and both parents employed or single parent households. There may be an increased cost in the future due to the expansion. For those with elderly parents needing care and children, this a great benefit which the current language is not able to control.
Our PWA now has a potential to enhance a benefit removing control from management. They have the power to interpret our PWA and if uncontested, set a precedent. With family sick their grip is loosened. They are not satisfied with the loss of control and regular employees having the right to care for their families. The "Delta" family takes precedent regardless of their rhetoric about caring and family.
