There is only one reason to terminate large numbers of employees at the same time

1. Cut costs

There are multiple reasons companies may need to cut costs. Generally, historically, they are not positive

One of them is that, internally, the business is not doing well or the company believes there are problems on the horizon

Perhaps a company that is healthy and optimistic about the future could at the same time be conducting successive rounds of layoffs

But are there many examples of healthy, shrinking companies from history

Usually company growth is taken as a sign of prosperity. Multiple rounds of layoffs are not. More like survival mode

But of course this time it will be different and the remaining employees after the layoffs have nothing to worry about
