The fight for Kent mill Co-Steel, put up for sale by its Canadian owner, is nearly over. A buyer is expected to be announced this week. The battle to win fairer work practices continues, however. A worker chained himself to the car of the Canadian High Commissioner, who visited the plant last week. Unions are protesting at the laying off of 19 active union members at the mill earlier this month. Trade minister John Battle has also joined the fray. In a Commons debate last week, Battle signalled he will investigate management practices at the mill in relation to the new Fairness at Work legislation.
