Unprecedented changes to the U.S. workforce are impacting small businesses in new ways, forcing them to adapt. But there’s one challenge that’s dwarfing all others: finding qualified talent in a tight jobs market.

Small business owners are trying various strategies to attract and retain talent, including offering flexible work hours, special bonuses, more paid time off and lowering out-of-pocket medical costs. While many smaller firms are focused on flexible schedules, larger firms are more likely to offer retirement plans, life insurance and flex spending plans.
