Doing pre-employment screening is important to ensure that people on the job are who they say they are, says Traci Canning, managing director of background screening at Kroll. Screening is especially important for financial institutions to ensure members' finances are being protected, she says. Before you start a pre-employment screening program, the HR and top management team need to set a policy, Canning recommends. When you set your policy, you are establishing certain thresholds for what you consider a risk, she explains. And for CUs with several branches, a detailed policy ensures everyone is using the same criteria. It takes guess work out of it, she says. Each CU will have its own set of red flags to look for, as determined in the pre-employment screening policy. But most companies will be looking for the same basic things.
