The Office for National Statistics said average weekly earnings rose by 2.5% on the year in the three months to May, slowing down from the previous three months when they grew by 2.6%. Pay growth excluding bonuses also slowed by a similar amount to 2.7%. The disappointing figures for pay growth came despite unemployment remaining at 4.2%, which was the joint lowest level since May 1975. While lower numbers of people out of work should help workers demand higher pay, some economists say the creation of low-paid and precarious jobs since the financial crisis has damaged the link between low levels of unemployment and wage growth.
