Microsoft may be one of the best companies to work for in the entire world, but the Redmond-based technology titan is constantly losing important employees.

This time, Christine Mullin, Microsoft UK's chief operating officer of its online and advertising division, has officially announced that she would leave the company, even though the reason behind her decision is yet to be revealed.

As a chief operating officer, Mullin was responsible for product marketing and business development and reported directly to Andy Hart, Microsoft’s advertising and online division general manager.

It’s not yet clear when Mullin will quit her job but, according to a report by MediaWeek, Simon Davies, who is currently holding the sales director position within the UK branch of Microsoft, will take over her responsibilities immediately after her leave.
