There are definitely better options though. At least warn people and give them a chance to make plans. Years ago I worked at a startup during the first dot-com crash. The president and the CEO had a falling out and decided to split up the company and spin the software development side into it's own biz under the former CEO. After a few months the upper management decided to lay-off 90% of the new company's employees without warning. All of whom previously worked at the parent company, some for several years. The few employees that weren't laid-off were told to stay home that day and none of the managers or the even the CEO showed up either. Everyone else came into work with a form letter waiting on their desks telling them they'd been fired. Nice to see nothing has changed in the industry over the past 20 years.
