Marking the second exit from the city’s top administration in a week, Finance Director Dale Walker has resigned his position after less than two years with the city.

City spokeswoman Debbie George confirmed Walker had resigned, but would not give a reason he was leaving. He was not fired, she said.

Walker came to the city in April 2009. As finance director, he was responsible for major accounting functions like payroll, accounts payable and accounts receivable, as well as some debt responsibility.

Before coming to Suffolk, Walker had retired from the city of Cadillac, Mich. He then had worked for the District of Columbia Retirement Board for about a year. That organization handles the retirement plans for the capital’s firefighters, police officers and teachers.

“I want to work, I don’t have to work,” Walker told the News-Herald during an interview shortly after he was hired.

Walker could not be reached for comment. He is the second high-ranking official to exit city hall this week.

City assessor Sid Daughtrey tendered his resignation Wednesday. His last day will be March 4.

Daughtrey, 55, said Wednesday he is leaving voluntarily.

“I just decided it’s a good time to see what else I can do,” he said.
