Port Macquarie MP Leslie Williams has called on the state government to hold an independent investigation into Essential Energy.
Mrs Williams highlighted the loss of some 180 jobs forecast to go in coming months and her fears that 'this may just be the tip of the iceberg'.
She raised the matter last week in state parliament calling "as a matter of urgency" for an independent investigation into Essential Energy.
Mrs Williams says she has spoken with a number of Essential Energy employees.
"Through face-to-face interviews, telephone conversations and emails they have reported their utter dismay, growing anguish and distress at the current management of the business, including allegations of misappropriation of resources, increasing operational costs, diminished workplace safety and bullying," she said.
Mrs Williams said employees also allege that the public commentary relating to efficiencies is a far cry from the reality.
"In fact, over recent years, expenditure has continued to dramatically increase to the detriment of local jobs," she said.
"Reports by employees both past and present of Essential Energy have been overwhelmingly consistent in highlighting a burgeoning senior executive to the detriment of frontline workers.
"Scrutiny of the Essential Energy Annual Report 2017-18 - page 54 - substantiates some of those concerns."
A spokesperson for the energy provider said Essential Energy has no comment at this stage.

In a further blow to regional jobs, the Electrical Trades Union says an internal Essential Energy document indicates plans for the energy provider to slash one in five regional positions by 2024.
The cuts will see an additional 500 workers lose their jobs on top of the 182 that Essential Energy last month announced would be cut from their workforce this year.
The ETU said the latest revelation highlighted the importance of urgent political action to develop a practical plan to save these jobs across regional NSW.
Since 2012, the workforce at Essential Energy has nearly halved as more than 2000 jobs have been lost.
ETU secretary Justin Page said the union was alarmed by the revelation that the current round of job cuts were just the beginning, with one in five workers at risk of losing their jobs in the coming years.
"Essential Energy has already been cut to the bone, we've seen the workforce almost halved in recent years and dozens of depots shut, so to discover that hundreds more jobs are on the line is alarming," Mr Page said.
"With one in every five workers facing the chop, there is no question that regional communities will be devastated and service delivery will be greatly impacted."
The union has written to Essential Energy CEO John Cleland outlining a series of proposals that provide alternatives to job losses.
The ETU has also provided a written briefing to NSW deputy premier John Barilaro outlining alternatives to job cuts.
"Our members have been extremely grateful for the supportive comments made by Mr Barilaro and many of his National Party colleagues, but those words need to be followed up with tangible actions if we're going to save these jobs," Mr Page said.
Mrs Williams met with the treasurer's office and the minister for energy and environment and says she is in ongoing discussions with the office of the deputy premier.
Essential Energy is a NSW-government owned company that operates the electricity poles and wires across 95 per cent of NSW.
