CVs must be watertight and there is no space for inconsistence. If after a quick scan the recruiter thinks you have potential for a role, often the next step will be to chronologically study your past work and education. Gaps in your CV in these areas are one of the first things they will home in on - make sure you either explain what happened in the gaps within your CV or have ready formed answers when you are asked at telephone or first interview. There are many legitimate reasons for these potential gaps such as family matters, illness or most commonly job searching - employers are very understanding of this situation after the past job climate so be honest and sincere. Lastly make sure you present any issues in a positive light by finishing your explanation on a high such as how you resolved it or how you plan to resolve it.
