This really isn't true. You aren't getting a paycheck, but in the case of Disney CMs you retain all other benefits of employment, from healthcare to tuition assistance (many soon-to-be-furloughed CMs are taking this opportunity to take advantage of this), seniority, etc. If you were truly laid off, you'd lose all of that and have to go onto COBRA, which costs a fortune and retain no other benefits.
Some of the furloughed people may eventually be laid off, just as they would be if they were still working and Disney had layoffs, but they are all still Disney employees for at least 12 months.
