Minister for Social Protection Joan Burton says she is working to ensure workers have the skills required by international investors but the government knows that smaller businesses need support too.
"For instance retraining people like construction engineers, architects, to transfer into the areas where there’s demand for labour – IT, medical devices and pharma" she said.
"In terms of the new investments we’re doing very well; Apple the 500 jobs, Paypal 1,000 jobs in Dundalk".
"But what we have to do then is try and spread that as well to the small and medium sector of start-ups" she added.
