asked the Minister of Labour if he is aware of the dissatisfaction felt by dock workers at Hull and other ports at having to sign, as unemployed, twice instead of once daily; if he is aware that, because he must sign between the hours of 9 and 10 in the morning and between two and three in the afternoon, many a man may lose a tidal job, or, on the other hand, because he has waited for such a job or gone in search of it from one dock to another, he may miss the opportunity for signing, and so forfeit his benefit; if he is aware that, on account of the inconvenience involved, there are many hardworking men who never sign on as un employed; and whether he will consider reverting to the practice of signing only once daily and of stiffening up the penalty for men detected in fraud, or take other steps to remove this grievance?
