Naomi Chial worked as a retail sales manager for Sprint when she complained to her boss that a fellow sales manager’s method of reporting sales amounted to “commissions fraud.” One month later, a supervisor warned Chial that her performance was slipping. Eight months and three written warnings later, the company fired her.

The final blow came June 24 from the 8th Circuit, which upheld the dismissal of Chial’s retaliatory discharge suit against Sprint/United Management Co. in a judgment that strictly interprets whistleblower protections in Minnesota.
