More than a century ago, in the expansionist wake of compulsory education, they knew a thing or two about incentive payments.
An 1875 advertisement by the Glasgow school board announced that several new schools were about to open and needed headmasters: “A salary at the rate of not less than pound;300 will be guaranteed for the first year, after which the income will depend very much on the success of the school.”
Sounds like new Labour.
