In March 2018 Lana Cormie's husband, the father of her two children, went to work and never came home.
Charlie Howkins was killed in Victoria while laying trenches for a construction company which was later charged with failing to keep a safe workplace.
Ms Cormie struggles to explain the devastation his death has had on the family, with her children aged just two and five.
"The impact on my family is indescribable. No one would understand unless they have been through it," she told reporters in Melbourne on Tuesday.
New laws introduced in Victoria's lower house on Thursday are aimed at preventing such tragedies, by threatening companies and their executives with huge fines or jail time if workers die as a result of their negligence.
Workplace manslaughter will become a crime under the laws, with a maximum jail sentence of 20 years and corporation fines of up to $16 million.
The laws were promised by the Andrews government before the last election.
Industrial manslaughter laws already exist in Queensland and the ACT, with a first prosecution under the laws in Queensland announced last week.
The Northern Territory parliament introduced similar laws to parliament in September and Western Australia is also considering changes, while advocates have called for them in NSW.
Up to 30 people die at work in Victoria each year, with the figure believed to be underestimated.
Victorian Attorney-General Jill Hennessy said people deserve to go to work and to come home safe.
"In this modern day and age, we should not be allowing businesses to have the loss of life included into their profit margins," she told reporters.
"It should not be part of anyone's business model."
The legislation will apply to small and large business across both private and public sectors.
It will also cover suicides caused by mental injury at work.
Ms Cormie said the law meant deaths like that of her husband have not been "completely in vain".
"Although I would never wish that people be lost for these types of laws to be brought in, the reality is that that has happened," she said.
"Many of us have lost our loved ones, and I guess, in a way, this is for them."
The legislation has been embraced by industrial law firm Maurice Blackburn, but the Victorian Farmers Federation is concerned they will disproportionally impact on family farms and businesses.
The farming group wants the government to exempt farm business owners from the laws, in the event that an immediate family member dies.
