a 2018 article for the Harvard Business Review, which notes:
Companies that shed workers lose the time invested in training them as well as their networks of relationships and knowledge about how to get work done. Even more significant are the blighting effects on survivors. Charlie Trevor of University of Wisconsin–Madison and Anthony Nyberg of University of South Carolina found that downsizing a workforce by 1% leads to a 31% increase in voluntary turnover the next year. Meanwhile, low morale weakens engagement. Layoffs can cause employees to feel they’ve lost control: The fate of their peers sends a message that hard work and good performance do not guarantee their jobs. A 2002 study by Magnus Sverke and Johnny Hellgren of Stockholm University and Katharina Näswall of University of Canterbury found that after a layoff, survivors experienced a 41% decline in job satisfaction, a 36% decline in organizational commitment, and a 20% decline in job performance.
