Some unions via their greed and inflexibility have caused businesses to go bankrupt. Or go out of business entirely. Read about Eastern Airlines.
And where possible, companies have moved U.S. jobs outside the U.S. where the wages are lower and they don't have to deal with inflexible unions.
But some union jobs can't be moved outside the U.S. Like jobs with cities, counties, and states. What is happening is some of these are quite broke and can no longer pay money into the retirement pension funds for their workers. (Some unions have demanded very early retirement, health benefits, and high pay for retired workers. Some governments can no longer afford to pay for this. Somethings has got to give!)

"public employers have little choice but to resort to layoffs, furloughs, five-year salary freezes and outsourcing as ways to cut payroll costs to "feed the pension dragon."

Bottom Line: Might be a better long term plan to NOT take a union job! (or don't count on having that job forever and don't count on any promised retirement.)
