That research paints a fairly consistent picture: layoffs don't work. And for good reason. In Responsible Restructuring, University of Colorado professor Wayne Cascio lists the direct and indirect costs of layoffs: severance pay; paying out accrued vacation and sick pay; outplacement costs; higher unemployment-insurance taxes; the cost of rehiring employees when business improves; low morale and risk-averse survivors; potential lawsuits, sabotage, or even workplace violence from aggrieved employees or former employees; loss of institutional memory and knowledge; diminished trust in management; and reduced productivity.
There are a number of myths that have taken hold to justify managers' urge to downsize. Many of them aren't true. For instance, contrary to popular belief, companies that announce layoffs do not enjoy higher stock prices than peers—either immediately or over time. A study of 141 layoff announcements between 1979 and 1997 found negative stock returns to companies announcing layoffs, with larger and permanent layoffs leading to greater negative effects. An examination of 1,445 downsizing announcements between 1990 and 1998 also reported that downsizing had a negative effect on stock-market returns, and the negative effects were larger the greater the extent of the downsizing. Yet another study comparing 300 layoff announcements in the United States and 73 in Japan found that in both countries, there were negative abnormal shareholder returns following the announcement.
Layoffs don't increase individual company productivity, either. A study of productivity changes between 1977 and 1987 in more than 140,000 U.S. companies using Census of Manufacturers data found that companies that enjoyed the greatest increases in productivity were just as likely to have added workers as they were to have downsized. The study concluded that the growth in productivity during the 1980s could not be attributed to firms becoming "lean and mean." Wharton professor Peter Cappelli found that labor costs per employee decreased under downsizing, but sales per employee fell, too.
