LINCOLN, Neb. (AP) – Employees who sell or serve alcohol in Nebraska would face mandatory training under a proposal lawmakers will consider to clamp down on underage and binge drinking. Omaha Sen. Steve Lathrop said Tuesday he will push a bill that would require state-certified training for workers who sell at bars, restaurants, grocery stores and other businesses. Lawmakers have tackled the issue numerous times in recent years. Some have tried but failed to enact a dram shop law, which would hold bars and taverns liable for drunken patrons who later cause accidents. Industry officials say such laws place an unfair burden on bar and tavern owners. Lathrop says he will either introduce a new measure when lawmakers convene in January, or work off existing proposals.
