HUDDERSFIELD'S MP is demanding a statement by company bosses after they failed to pay workers on time.
Labour's Barry Sheerman said he was extremely worried about the situation at Longroyd Bridge engineering firm Brook Crompton.
He said: "I shall be attempting to contact the managing director about this.
"It is not good and needs an explanation. I hope it is just a glitch."
Worried monthly-paid workers finally got their salaries paid into the bank on Christmas Eve, after expecting to receive them the previous week.
But weekly-paid workers will not get their money until January 6, it has emerged.
Thirty-five workers made redundant have also been told they will be paid on the same date.
New Singapore-based owners took over the St Thomas's Road factory in a £17m deal this year.
Mr Sheerman said: "It's very worrying when you have got a new employer and something like this happens.
"People need their money - especially at this time of the year."
No explanation has come from management about the delays.
The father of one weekly-paid worker said: "We've stuck with this firm through thick and thin - and end up being treated like this.
"It's sickening and we're all wondering what's happening."
Workers were laid off after the takeover when the new bosses said they were stopping making electric motors on the site.
Remaining staff are employed in customer service, warehousing and distribution.
The factory re-opens after its Christmas and New Year break on January 6-- the day when weekly-paid workers have been promised they will get their cash.
No-one at Brook Crompton could be contacted for comment.
The firm changed hands when it was sold in February by parent group Ivensys to cut massive debts.
Within weeks, new owners Lindeteves-Jacoberg announced the end of manufacturing of electric motors. Work would be transferred to plants in Guiseley, near Leeds, Birmingham and Poland.
