"techs found themselves finishing work at 3am but having to vacate the motel room at 10am"
Planning would have made a huge difference e.g. arrangements with the motel, not booking with the cheapest motel available - it will come at a cost but you cannot use $ as a reason not to provide suitable accommodation. I worked in an industry before where we experienced the same problems and Managements/Project Manager H&S culture needed to be addressed and changed. It took a while but with H&S Reps, and employee engagement we changed from being reactive to proactive and management had to accept that employees value their own safety.

Our H&S Reps have a job description.
