The group chief executive of NTUC Enterprise has resigned and will leave on Feb 28.
Mr Tan Suee Chieh was appointed director of insurer NTUC Income in 2003 and was its CEO from February 2007 to September 2013. He left the insurer to take up his role at NTUC Enterprise on Oct 1, 2013.
NTUC Enterprise - the social enterprise arm of labour movement National Trades Union Congress (NTUC) - will conduct a search for a new group chief executive over the next few months, it said.
It noted that Mr Tan, who has been with NTUC and its various social enterprises for 13 years, "will continue to maintain his ties with the labour movement by continuing to hold directorships at NTUC Foodfare and NTUC Link".
Mr Tan said in a statement: "It has been an incredible three years being the first group chief executive at NTUC Enterprise.
"We have laid down important foundational work to ensure the long-term success of the NTUC Social Enterprises (which includes NTUC's insurance firm, supermarket, coffeeshop and pharmacy chains).
"We also created a multi-functional operating head office to plan and operationalise strategic decisions for the group."
He noted that it was a good time for NTUC Enterprise to have new leadership "to take it forward in its next stage of its development" and added that any announcement on his new appointment will be made in due course.
In a memo seen by The Straits Times, Mr Tan also wrote about looking forward to seeing the social enterprises "scaling new heights", as employees "continue making great social impact for the people and the community you serve".
NTUC Enterprise chairman Lim Boon Heng said: "During his three years as NTUC Enterprise's first group chief executive, Suee Chieh has contributed to laying a strong foundation for the group for the future.
"Our social enterprises, comprising NTUC FairPrice, Foodfare, Income, Health, First Campus, LearningHub, Link, and Mercatus, are now a cohesive group, with a clear long-term strategy to deepen our social impact and to create and enhance value for the labour movement."
