(undated) — State officials are preparing to join the effort to put more Massachusetts citizens to work. The commonwealth next month is planning what’s being billed as the “largest virtual job fair” in Massachusetts history. The intent is to help both companies in need of new employees, but also the nearly 330,000 unemployed in the state who will see their expanded unemployment benefits expire in September. An exact date for the on-line event has not been announced.
