Nursing home workers from three of the biggest chains in the state voted Monday to send unfair labor practice strike notices for what they claim are the companies’ failures to provide information about agency staffing and costs, and for not bargaining in good faith. By law, nursing home administrators must receive a 10-day notice before a strike at a healthcare facility takes place. The union claims that its workers are being offered lower raises than last year despite nursing homes receiving a $600M investment in funding from the state budget.
