A layoff can come for many reasons, such as a merger or spin-off or economic changes. Most workers will detect some warning signs, such as seeing a manager's office doors closed more often and having formerly positive feedback on job performance suddenly turn negative, [independent IBM consultant Jamie] Giovanetto said. Memos outlining new cost-saving initiatives or "stupid cost-cutting" measures, such as reducing office supplies, are another tip-off, he said. He recommends reading a company's Securities and Exchange Commission filings, as well as networking with customers and competitors who may have insights. Avoiding a layoff requires you to give the best you can on the job, but even little things can make a difference, Giovanetto said. Working at becoming a subject-matter expert and keeping a clean, organized and professional-looking work space may lead to better assignments. "It's just an appearance thing, but it does pay benefits," he said.
