According to information obtained by YLE, investigations are examining the alleged psychological abuse of Räty's former secretary and dismissed communication chief Hilkka Ahde. Räty denies any wrongdoing.
Last week, police completed an investigation into accusations against the Transport Workers' Union (ATK) chairman of workplace harassment. At that time, investigators confirmed that Räty was also suspected of violations of workplace safety laws. YLE has now received information according to which the suspicions centre on psychological abuse.
'Crossed the line'
In practice, police suspect that Räty's behaviour crossed the line into the area of psychological assault against both then-communications chief Hilkka Ahde and his own former secretary.
The abuse is thought to have begun in 2005. Police have gathered testimony from several individuals who say that Räty's behaviour towards both was inappropriate.
Those questioned in the affair say that the union boss shouted at Ahde and his secretary, and for example, for three weeks last year refused to have any contact with the union's communications chief. According to the investigation, the entire staff of the union's central office was aware of his inappropriate behaviour, but the situation was allowed to continue.
The information gathered by YLE indicates that in addition to Räty, five other current or former union officials are under suspicion of workplace safety violations and causing injury. The possible charges relate to not intervening in Räty's suspected abuse of staff.
