How many road workers does it take to change a light bulb?
Taken at the junction of the A30 and M5 in Somerset, the photo shows one worker atop a ladder checking the lights, with six of his colleagues standing around twiddling their thumbs.
The men all belong to a private firm carrying out contract work for Devon County Council and had been ordered to check the signal lights as responsibility for maintenance of the road is handed over from the Council to the Highways Agency.
The picture, taken by Karl Baker, was posted to his Facebook account with the following comment: "Words fail me! Good to see Highways are helping to reduce local unemployment."
The photo prompted others to poke fun at the workers. Adrian Morgan commented: "Standard workman rules: 10 watch, 1 works!"
A spokesman for Devon County Council said: "The work being carried out was not at the expense of the taxpayer and these are not County Council employees," reported the Daily Mail.
"The contractor was on site to check that the traffic signals are set up in accordance with strict specifications before the maintenance of the signals is handed over to the Highways Agency.
"The contractor is covering the cost of the final checks and adjustments and they decide how to conduct the work."
