Tin Pei Ling announces in facebook that she quitted Ernst & Young to become full-time MP

Facebook.com, 31 May 2011
Yesterday (31 May 2011) marked my last day with Ernst & Young. After long and careful deliberation, I decided to resign from the firm to focus on my responsibilities in MacPherson and Marine Parade GRC. Working as a business consultant has been enriching and meaningful, and I deeply appreciate the confidence and opportunities that the firm has given me over the years.I have now been on the ground in MacPherson for over two months. MacPherson has a large number of elderly and poorer households. I feel strongly for them. They require and deserve more help and attention, and there is still much that can be done for them. I have decided to spend more time on the ground, to better serve the needs of residents, and to implement my plans for MacPherson.
I will consider my longer-term career plans in the future, but fulfilling my duties to the residents of MacPherson will remain my first and utmost priority. Link
