Charles told his boss he was quitting his job. He then received a shocking text message that left him speechless; you won’t believe what it said

A former employee has shared an incredible text message he says was sent by his boss after he resigned from a failing company.

Charles, who did not want to use his real name, said he left Vallec electrical and mechanical services company five years ago after he felt it was on the brink of collapse.

The NSW-based company, led and partly owned by Tobias ‘Toby’ McCosker, folded just two months later.

“They had a huge tax bill. They were in arrears with suppliers. I saw the writing on the wall,” the former employee said news.com.au.

He claims that shortly after he quit he received an aggressive text from Mr McCosker.

“My final message to you is that you are a f***ing b***h who can’t deliver anything but a box of farts that will price you (sic) of sh*t,” it read.

“Every damn day of the week you w*gc**t.”

Vallec went bankrupt along with two other related companies, headquartered in Newcastle, with debts totaling more than $7 million.

It is understood Mr McCosker worked at Vallec with Mike Arnold, who was declared bankrupt a decade ago and banned from running his own business.

The former employee said Mr Arnold had a key role at Vallec.

It is understood they were also involved with another construction company, Workspace One Pty Ltd, which collapsed last year.

Liquidator Liam Bailey suggested in his statutory report to the regulator that Mr Arnold was the shadow director of Workspace One.

The actual director was Mr Arnold’s wife Kathryn, but it was claimed she ran the company in name only as Mr Arnold was forbidden to use his.

Mr Bailey also accused Ms Arnold of taking $861,000 before the collapse of Workspace One – more than enough to cover the company’s debts of $845,000.

She previously said she transferred the money to her personal account to reimburse business expenses.

Contractors who worked with Workspace One last year said they “never met” Ms Arnold, despite her being the apparent director of the company.

“He (Mike Arnold) was basically a project manager, he managed all the transactions, he was basically the man, he was everything,” said one creditor.

Rhys Clarke, of Cools Electrical, said he only realized Ms Arnold was the director of Workspace One when his company went against hers in court.

Mr Clarke added that Mr McCosker had a “mind-boggling” advisory role at Workspace One.

‘His title was very unclear. I knew he was an electrician. I knew he had done something in the electric air conditioning industry before. But very unclear. It was strange having him there,” Clarke said.

However, he said it was “very clear” that Mr McCosker and Mr Arnold were friends.

During Mr Bailey’s investigation, which he submitted in a report to the Australian and Securities Investment Commission (ASIC), he described Workspace One’s accounting skills as ‘appalling’.

It is understood Mr McCosker worked at Vallec alongside Mike Arnold (pictured), who was declared bankrupt a decade ago and banned from running his own business.

He was forced to seek the help of ASIC to order Ms Arnold to hand over the missing documents to the liquidator.

ASIC brought civil proceedings against Ms Arnold last year and she was fined $500 for failing to prepare a statement of company affairs and $1,000 for failing to deliver books to Mr Bailey.

Following the collapse of Workspace One last year, the Arnolds moved to the Mid North Coast, where Mr Arnold now worked alongside Mr McCosker at another construction company, Alurt Construction.

Daily Mail Australia has contacted Mr Arnold and Mr McCosker for comment.
