"Suck up some new lingo" joke

Copied from the Houston Chronicle:
Language changes to reflect cultural shifts. And in this period of skill shortages, flexible work arrangements and global business deals, new workplace jargon was bound to pop up. So you're not caught off-guard at the next corporate luncheon when someone refers their employee as a "job vacuum" or "border crosser," here's a handy reference guide courtesy of Challenger, Gray & Christmas, the Chicago outplacement firm.
Job vacuums:
Employees who voluntarily sweep up extra duties; show strong work ethic.
Border Crossers:
Multi-skilled employees who feel comfortable jumping from job to job inside a firm.
Soft benefits:
Nonmonetary enhancements.
People churner:
A bad boss who often is blamed when a company can't retain its key employees.
Protected class:
Rank and file employees with critical job skills.
Boomerang workers:
Retirees returning to their previous employer.
Toxic:
Worker with anti-management reputation who is often litigious.
