The accompanying list describes the responses of four individuals to a Bureau of Labor Statistics (BLS) survey of employment.
(1)- Mollie just graduated from college and is now looking for work. She has had three job interviews in the past month but still has not gotten a job offer.
(2)- George used to work in an automotive assembly plant. He was laid off six months ago as the economy weakened. He expects to return to work in a few months when national economic conditions improve.
(3)- Jeanette worked as an aircraft design engineer for a company that produces military aircraft until she lost her job last year when the Federal government cut defense spending. She has been looking for similar work for a year, but no company seems interested in her aircraft design skills.
(4)- Ricardo lost his job last year when his company downsized and laid off middle-level managers. He tried to find another job for a year but was unsuccessful and quit looking for work.
