As the closing date approaches for the doomed factory, long-term staff have told the Sentinel they are set to lose out on thousands of pounds from pay-off packages because of warnings issued over alleged minor disciplinary matters.
Trade union officials have confirmed that several concerned staff have contacted them over the potential slashing of four figure sums from final payments and labelled the company's human resource policy as "draconian".
One worker, who did not wish to be identified, said he stands to lose out on £8,000 because he was issued a written warning earlier this year.
"I was given a written warning in January for what they call non-notification, meaning they claim I did not call in sick. I had called in five times. I have been told that I will not receive the second element of my payment.
"I stand to loose two weeks of the agreed six weeks payment for every years service. I have worked there eleven years so this adds up to £8,000," he said.
The worker also claimed that before the announcement of the Limavady plant's closure a warning of this nature would remain on an employee's file for six months before being erased.
But, he said the company have allegedly extended this policy to a period of nine months, meaning many more workers may have money slashed from their payments.
"On my shift alone I know there are at least seven people affected. I thought this company had my interests at heart but they are just working to their own agenda. £8,000 may not be a lot to them but it is to me. They don't think about people with families", he said.
Liam Gallagher, Secretary of the Derry Trades Council, said he was aware of another case where a women stands to have £7,000 wiped from her final payment in a wrangle over sickness. And, another man, Mr Gallagher said stands to lose out on £9,000.
"This woman was genuinely ill but has been told it will have a material affect on her redundancy. This is symptomatic of companies who refuse to recognise unions and operate draconian human resource policies. It's a disgrace that these type of industrial relations are in operation in 2008."
Whilst Seagate have confirmed the cessation of production has been brought forward to September 25, the worker who spoke to us said employee's are expected to remain available for work until the original closing date of October 31.
The worker said: "Even though work will have stopped we have been told that if we are not available for work we could loose all our money.
"This means we cannot go on holiday, unless they were previously booked and cannot accept new employment."
East Londonderry MP, Gregory Campbell, told the Sentinel: "I am aware that a number of people with alleged time keeping difficulties may have got into conflict over their redundancy packages. I hope the company would treat sympathetically what for these employee's a long-term association with the company."
A spokesman for Seagate responded by saying: "Production will cease on 25 September but employee's will be paid until 31 October. We are not going to comment on what are individual employee matters."
