Resume Gaps

Do you have a preference for contract or short term assignments?
If the answer is yes than your CV may be very long and can be a negative in an employers eyes. Ways in which you can cover resume gaps include turning the attention away from your employment dates & writing just the years of employment (you can clarify dates later on if need be) or put all short terms jobs in one group as a whole - you can put a title for this work under "consulting or freelance work".
