It is evident, and Senator O'Toole touched on this point, that society is changing rapidly and that what might have appeared to be reasonable and desirable protection ten years ago needs to be reviewed now. Legislation of this nature must be kept under constant review. As recently as ten years ago it would have been regarded as normal practice for somebody to take up a job in their mid or late teens and remain in that job until retirement at age 65, but people are now retiring earlier. The classic cycle of growth and decline in companies is much more rapid now than ten or 15 years ago and people have to be mobile within the workplace and even within the country in terms of moving to employment. There is evidence of that in the greater Dublin area, particularly in Kildare where people have moved in significant numbers over recent years.
