Mr Gallagher said E tu had emailed Top Energy, detailing its concerns for workers' safety in the light of the accident. The union is calling on the company to urgently consider its submission, which seeks halt the restructure until a proven fatigue management system is in place.
"Workers have voiced fears that the cuts are too drastic and will compound problems with fatigue and stress, resulting in more accidents," he said.
"We want the company to urgently consider what we've said in our submission, and halt its restructuring process so safety issues can be carefully traversed. There should be no job cuts until everyone is satisfied that workers will be safe."
Mr Shaw said an initial investigation had been undertaken into the circumstances of the accident.
"We are satisfied it was not related to fatigue. The injured worker was fully rested. He was on standby duties but had not been called out overnight. The accident occurred during the middle of the day when the height of the storm had passed," Mr Shaw said.
"Top Energy has an established fatigue management system in place which is continuously monitored, particularly during storm events. This policy was initially developed and has been updated in consultation with staff and the E tu."
Mr Shaw said the company's priority was for the speedy recovery of the injured worker and Top Energy would be supporting him while he healed from his injuries.
