Member Support Committee -- New Employee Orientation and Membership Benefits

  • Explore ways to improve current maternity/paternity leave benefits for Bargaining Unit 9 (BU 9). Winter 2019/ongoing.
  • Member Appreciation Care Package. Summer 2020.
  • Supervisors Appreciation Care Package. Winter 2020.
Maternity/Paternity Leave Initiative

Current Maternity Leave Benefits
The State’s outdated Maternity Leave program offers six weeks of leave only for females. The amount of supplemental income also depends on the type of leave program the employee is enrolled in. Male employees and adoptive parents are not eligible to receive compensation for time off for leave. The limited leave time may generate strain and difficulties during a time when the health of our members is vital. In addition, complications during pregnancy and unforeseen events can create financial stress on our members and/or their partners during.

Proposed Maternity/Paternity Leave
The Committee is exploring the support of 12 weeks of paid family leave for both male and female BU 9 employees. This approach will use the current benefits offered under the State Disability Insurance (SDI) program as a guide to determine who will be included. This proposal will provide paid leave and an increase of wage replacement percentage to allow BU 9 employees time to bond with their child and lessen the financial burden while on leave. This proposal will:

  • Reduce the inequalities in family leave between BU 9 employees and the private sector and other bargaining units that have SDI.
  • Contribute to the healthy development of a BU 9 employee’s family.
  • Promote time-off for parents and caregivers to care for and bond with very young children without jeopardizing their income.
  • Promote family financial preparedness.
  • Could help increase the percentage of women working in BU 9.
  • Incentivize younger professionals to seek a career in state service and learn from our veteran staff.
  • Promote a healthy work-life balance.
  • Support Governor Newson’s goal to expand Paid Family Leave in California.
Committee Meetings
As of November 2020, the Committee meets about once a month to discuss the items above. We welcome our River City Section members to drop in on a meeting to hear more about our activities! If you are interested in learning more about the Member Support Committee, please contact
