Paranoic, neurotic, impulsive driver.
Driver was hired, in the office was acting normal, but when left the office - started to complain non stop. He was taking detours to make more miles, and company was loosing on gas. Refused to work, stopped on the shoulder of the road, with loaded trailer, did not make the deliveries in time. Wanted money to be paid upfront. When company refused to pay upfront - started blackmailing us.
