I agree with you that a labor efficiency expert can really help workers do a better or faster job, but I've seen problems, too. Sometimes a company will hire these efficiency people to make themselves feel better about downsizing or layoffs. Maybe one employee could take over the duties of another employee, but that isn't always a good thing. One employee loses a job and the other one gets overworked. I think companies need to keep their labor force as efficient as possible, but sometimes you need more than just an efficiency expert's opinion before doing something drastic like cutting a workforce.
