Give it enough time and your hourly wages will amortize to cover this - what should now be a 75/hr tier will have remained at 60/hr because everyone gets paid that, working overtime, to get some job done that probably doesn't need overtime to get done.
Saw this in Oil and Gas industry among Engineers and Designers (the pipeline/wiring kind, not the UX kind), not sure if it's true for other industries though. Haven't worked contract in software yet to see for myself.
