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The State’s outdated Maternity Leave program offers six weeks of leave only for females.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

Director:  Kevin Pfeiffer
It has been an honor representing this Section in the previous year as the Section President. One of the great joys I have had in this position has been seeing the continued development of interests and networking opportunities and the resources provided for members through our exciting committees. Expanding these committees and the resources provided by them will be one of my top priorities as Director. I also remain committed to voicing members’ concerns on issues like pension expansion and protection, increasing time off and work flexibility, and family leave. This tumultuous year has laid bare the importance of quality health care in all regions, and I promise to act as a voice for rural health care subsidies at the corporate level. As your Director, I look forward to the opportunity to make PECG and the River City Section a union that works for all members regardless of where they are in their careers.

President (per Section Bylaws):  Tim Chow

President Elect:  Khristina Keyba
I know I thrive the most when I can interact with others. I see this as a great opportunity to grow in my career and thrive as a person, to move onto President Elect. In order to successfully perform the duties listed for the position, I believe, requires someone with sound oral and written communication skills; as well as someone who is genuine. In my career, I was and am still able to effectively communicate and collaborate with customers and colleagues. In High School and College I’ve held leadership positions and took the lead in quite a few group projects. Being mindful of how much our volunteer time can impact our members is what I believe will make a difference for the River City Section. Thank you in advance for your time and consideration.

Vice President Rank and File:  Brandon Roosenboom
Brandon is a Water Resource Control Engineer at the California State Water Resources Control Board in the Division of Water Quality’s NPDES Industrial and Construction Stormwater Unit. Brandon has been a PECG River City member since 2018 and participates on the Philanthropy Committee, seeking opportunities to better serve our communities and environment. As VP Rank and File, he hopes to engage with members of the union to represent their views while also hosting outreach events to expand our membership.

Vice President Supervisory:  John Murphy
After enjoying the countless benefits PECG has provided in tenure as both a PECB member and state employee, I am thrilled to give back and pursue a leadership position in the River City Section. As a Senior Engineering Geologist with the Central Valley Water Board in Rancho Cordova and licensed Professional Geologist and Certified Hydrogeologist, I hope to leverage my leadership experiences to represent state supervisors in our region and act as a liaison for any issues that arise. Extracurricular leadership activities have always been a passion (e.g. I am the current President of the Sacramento Chapter of the Association of Environmental and Engineering Geologists (AEG)) and I look forward to the challenges the VP Supervisory role will provide. Thank you for your vote and support and feel free to reach out any time!

Vice President At Large:  Emily Cushman
I’m an Engineering Geologist working for the Regional Water Board in South Lake Tahoe. I’m running to be the River City Vice President-at-Large to support our member’s interests and continue to strengthen our union. I would be honored to continue to serve in this role for another year.

Secretary:  Bryan Moore
I have been a PECG-represented employee for the last four years.  Prior to entering state service, I worked in private industry as a non-represented employee.  Through these experiences I have seen firsthand the benefits of having strong labor representation in your corner to fight for better pay, benefits, and fair treatment.  As a PECG River City Section officer I will do what I can to further the interests of members, strengthen the Section as an organization, and, as Secretary, ensure continued transparency for officer meetings.

Treasurer:  Raja Ramesh
I currently work as an Air Pollution Specialist at the California Energy Commission. As part of PECG’s River City Section, I’ve appreciated the opportunity to work with other members to increase awareness of support resources and engage across agencies. If elected as Treasurer, I’ll work with other officers to ensure our section’s funds are responsibly managed.
