The communication from upper management is terrible (CE* management might be the industry's worst as the push for near term profits is propped up by relentless cost cutting).

Recent layoffs have forced talented employees out as the company's current priorities are not to find ways to retain good employees to invest in new projects and products, but rather to eliminate unwanted lines of business and maximize investor returns. For an employer with so many job openings, freezes and blindly laying off groups loses employees that could have readily filled other roles at the company.
