A union survey showed 83 per cent of respondents had suffered a workplace injury or illness.
And more than 7000 Tasmanians made workers' compensation claims last financial year.
Unions Tasmania secretary Jessica Munday said she was "disappointed but not surprised" by the result of the Australian Council of Trade Unions' recent work health and safety survey.
Ms Munday said the national Work Shouldn't Hurt survey attracted more than 26,000 respondents with 1200 Tasmanian workers having their say.

She said some of the key Tasmanian results of the survey included:
- 83 per cent of Tasmanian respondents have suffered a workplace injury or illness;
- 79 per cent know someone who has been seriously injured or become ill because of their work;
- 62 per cent have suffered a psychological injury or illness due to work;
- 78 per cent believe the penalties faced by employers are not enough to make them take health and safety seriously.
Ms Munday said the figures were slightly higher than the national results.
"These are terrible results and give us an indication of how unsafe Tasmanian workplaces are," she said.
Ms Munday said she believed the number of workers' compensation would be more but many employers actively discouraged workers from lodging claims.
"We believe that number to be much higher with many workers not claiming workers compensation, especially for psychological injuries, because of the stigma and grief the process causes them," she said.
"We need all levels of government to take action to make our workplaces safer and to act on the Boland Review's recommendations."
Community and Public Sector Union delegate and child safety and well-being worker Katie Holmstrom said workers in child safety were at high risk of psychological and physical injuries.
"We work with people when they are at their most vulnerable and stress leave is a regular occurrence in different areas," Ms Holmstrum said.
"Workers suffer vicarious trauma. If there were tighter injury laws it could be helpful in retaining staff."
The Boland Review, commissioned in 2018 to look into Australia's work, health and safety laws, made 34 recommendations.
