The communications director for Mayor Martin J. Walsh resigned Friday after just four months in the post, marking the first shakeup in the fledgling administration.
Lisa Mansdorf Pollack said she submitted her letter of resignation Friday morning and would return to her previous post as director of public relations at the Department of Neighborhood Development.
Pollack said she was not pressured to resign by the mayor’s office.
“This was me saying I want to step down,” Pollack said. “This was a moment when I realized that I needed a different quality of life, but that I still very much wanted to serve the administration.”
The administration intends to fill her position, Pollack said, adding that it will take time to find a replacement. Pollack was a member of Walsh’s Cabinet and is the first person he hired who has stepped down.
Pollack began her career in government as a photographer for Mayor Thomas M. Menino and later worked in his press office. Pollack then spent nine years handling corporate and crisis communications at the Denterlein public relations firm before returning to the city and the Department of Neighborhood Development.
As communications director for Walsh, Pollack held the same title Dot Joyce did under Menino. The job demands long hours, and Pollack said it took a toll.
Pollack has a 3-year-old daughter. She said that her hours as communications director kept her away from home too long.
“Recently, my daughter turned to her father, ‘Daddy, that was fun having Mommy home yesterday,’ ” Pollack said. “And I realized that although I love this work and that this is the dream job . . . it might not be the right time for the dream job.”
