Once Hastings Mutual became a general line insurance company, it was necessary to have agents who were qualified and licensed by the state as general agents. The company sponsored a school and brought in 80 to 90 agents for training. Thus began the successful relationship with trusted, agency partners.
By 1967, Hastings Mutual had broadened its coverages to include farmowners, inland and ocean marine, general liability, burglary and theft, and Workers' Compensation. Automobile insurance was added in 1970.
Since first moving into the new building, the number of employees had doubled, so ground was broken for a 30,000 square foot addition in 1980. Shortly after, the data processing age brought the development of an automated policy processing system.
Expansion continued through the close of the 20th century. The home office completed a second building expansion in 1991. Hastings Mutual entered the state of Wisconsin in 1994 and the state of Illinois the following year and in 1999 the first company website was launched.
