Updates from our Facebook page
We are sad to share news of the passing of former CSO President Don Hillman. A longtime CTA staff member and CSO President from 2009-2013, Don is fondly remembered as a gentle presence in any room and his leadership was described as decisive, thoughtful and kind. Don was respected and loved by CSO and CTA members alike, and we are all better for having him in our lives. We send our love to Don's family and loved ones. May his memory forever be a blessing.Please join us in tipping a glass for an amazing colleague, friend, union brother and human. Rest easy, #WeAreCSOr#WeAreCTAreCTA
