Got that sinking feeling, huh ?
It has been my experience that there isn't really anyone out there who will be interested to help unless you are prepared to pay money. Clearly many companies (and others..) profit from the workforce being starved of accurate and pertinent information concerning their rights as employees, and a timely and effective "watchdog" to champion their cause.
Try this;
www.dti.gov.uk
This a U.K. website which you can browse but it obviously doesn't cover the Republic of Ireland.
Good luck !
