The big picture is not just with this particular DPS employee, but the entire state and city civil service system.  It's one of the biggest reasons why we have a bloated, inefficient and corrupt workforce.  In what private industry can you get away with criminal activity and not be terminated?  Employees on PAID leave for years while they are investigated, with little more than a slap on the wrist, or eventually retire with full benefits.  If there is no downside to doing the job correctly and with honesty, then something needs to change. 
The unions run government work.  Nothing can be done without union approval even if the employer, paying the wages wants to change things.  Thus, where does that leave our state and city?  Bargaining with the union in order to get things done.  Where is the taxpayer in this equation?  Without representation from the elected body and held hostage by the unions that run the state.  We pay to continue the corrupt madness of government in Hawaii.
