I worked for an agency until December 27 2014, but my contract ended unexpectedly on that date. I had 2 weeks of unused holiday pay. I have sent a request for my P45 and unused holiday pay but They stated that they cant pay me anything for the unused holiday as the holiday year ends in December and I didn't apply for it. Is this legal? Can I get my holiday pay entitlement or is it lost forever?
