Six per cent of businesses were affected by industrial action last month as disputes over pay, jobs and working conditions led to worker protests.

Of businesses affected by strikes, nearly a third said their workforces had not been able to perform their roles as a result, while another 20 per cent said staff had been forced to work from a different location. Healthcare and social work were affected most, comprising about 10 per cent of businesses hit by industrial action last month.

The proportion of businesses reporting strikes was roughly the same as in June, according to figures from the Office for National Statistics.
