Depends. Maybe yes, if you only had 2-3 contract positions, 回复：s

But if there were 5-10 contracting positions, it should be a better way to put in resume - open for discussion.

After 15 years in the large Corporate, I am planning to do contract work in next 5-8 years until retired, with each 6-9 months.
That's why I'm thinking forward for future resume writing formats, as I'll start a contract next month and will look for new contract work 2015.
