Liverpool (CNN) -- UK police and emergency services were heavily criticized Wednesday for their handling of a tragedy at a soccer ground in 1989 in which 96 people died, after an independent panel for the first time reviewed thousands of documents previously kept out of public sight.
But Manuel Atienza, of the General Workers Union (UGT) said the strike will have more impact as it continues, because overloaded ground crews, even while complying with legally-mandated minimum services, will fall farther behind on tasks like baggage handling.
