The document discusses the challenges faced by a UK council in bridging workforce gaps and achieving efficiencies of £100 million with 5,500 fewer employees by 2015. The council's approach involved greater customer focus, collaborative leadership, engaging and empowering employees, avoiding mass redundancies, better deploying talent, and sticking to core values. Through this approach, the council closed 20 buildings, relocated 3,300 employees with 1,500 working flexibly, achieved £100 million in savings, and reduced the workforce from 8,400 to 6,300 without redundancies. Ongoing challenges include further improving outcomes and efficiencies with additional headcount reductions.
