ACC staff are on the receiving end of a growing number of threats to the organisation, with one client saying his case manager "was lucky he didn't shoot her".
ACC claimants threatened the organisation 300 times in the year ended June 30, 2012 and the union representing ACC staff says the increase appears to have a direct link with the organisation's well-publicised privacy breaches.
Of those, 134 threats were aimed at staff, 67 at the organisation and 33 at providers such as physiotherapists, occupational therapists and doctors. Sixty-six clients threatened self-harm.
Public Service Association national secretary Brenda Pilott said the frontline staff bore the brunt from systematic failures and breaches that occurred at much higher levels.
