I've been in the same secretarial role for many years and have decided I'm going to start searching for a new role so have been updating my CV over the Christmas break. My CV as it currently stands has all the jobs I've had since I joined the workforce age 17 in the 1980s - this means it runs to several pages and I've been reading that a modern CV should only be 2 pages. I'm wondering how many years job history to include? Do I just include, say, the last 10 years but if so won't prospective new employers wonder what I did in all the intervening years?
