The government is coming under increasing pressure to co-ordinate rehabilitation services, in order to slash the rising cost of work-related illness.
The ABI and TUC have called on the government to improve its efforts after a joint consultation exercise found rehab services cost the taxpayer £14 billion a year.
Both parties are demanding more action, saying the results show the extent to which the UK's system of rehabilitation needs to be improved.
John Parker, the ABI's head of general insurance, said: "Britain's rehabilitation services are far from healthy. This consultation confirms those workers; their families, employers, and British industry are all paying a high price for workplace injuries, because of the piecemeal approach of getting ill workers back to work.
"The ABI/TUC joint consultation exercise has highlighted that there is clear consensus for change. The challenge now is to seize the opportunity to bring about long -lasting improvements in rehabilitation services."
The warning comes ahead of joint ABI/TUC conference to be held on 28 January. The meeting will call for a national action plan to bring about improvements in the provision of rehabilitation services.
