There are three good reasons why the incentive scheme should recommend itself to miners in this week's ballot.

First, it was devised to avoid the evils of past piece-work schemes which set men against men and lowered safety standards. This new scheme, which was worked out by those who know the industry best, is based on machine power and not muscle power to get the coal that Britain needs.

Secondly, it comes at a time when the longer-term expansion of the coal industry has been agreed and when an integrated national energy policy is becoming a reality.

Thirdly, it offers the prospect of an increase in pay now for all mine workers.

I hope—and believe—that the miners will give the scheme a fair trial.
