I would say the only downside maybe, just maybe, the contract situation most of the work will be done. If someone isn't comfortable with being in contract work, I can see where someone may find it hard to be satisfied. However, the great thing is that UNCOMN, always reassures there will be work available for you. They won't just let you go because your contract with a project has ended, they make sure that you're taken care of and will swiftly queue in another contract for you.
