3. Construction and its components: The slumping housing industry has taken a toll not just on home values but the jobs that go into creating new homes. Manufacturers of wood products have slashed 4.9% of their work force. That includes 21,300 jobs related to furniture manufacturing. Overall construction lost 208,000 jobs, with the residential building industry losing 39,100, or 4.3% of its workforce. Especially hard hit were specialty trade contractors for residential construction, whose workforce contracted 4.7%. Those workers lay the foundations for buildings, perform exterior work, install mechanical systems and make repairs. 4. Temps: When making the choice between the salaried employee and the temporary help, employers have been slashing temp jobs left and right. Through May, 113,900 of those workers have been left jobless, representing a decline of 4.4%. 5. Postal workers: Believe it or not, Post Office employees are among the top workers looking out for pink slips. The agency has cut 29,800 jobs so far this year, a decline of 3.9% from the end of 2007. If only job-hunters were mailing out their resumes instead of submitting them online.
