ST. PETER, Minn. -

Construction crews are finishing a $56 million expansion to the Minnesota Security Hospital in St. Peter.
    
The Department of Human Services says the addition's modern design is much safer for both staff and patients. Hospital director Carol Olson says it will be easier for staff to monitor patients, and that smaller units will make it harder for patients to hurt themselves.
    
The president of the union that represents hospital staff says safety conditions are improving slowly. But Tim Headlee says that workers still aren't getting all the training they need, and they're too often subject to mandatory extra shifts.
    
Human Services Commissioner Emily Piper says Gov. Mark Dayton plans to ask lawmakers to authorize millions more dollars for new construction and more workers.
