This is generally speaking not a problem. It's technically possible, but generally in at-will states in the US, for exactly that reason, there is a strong incentive to not "randomly" lay people off b/c the company gets a reputation for being unpredictable and people don't feel secure in their jobs. They start to view their jobs are more transitory and it erodes company loyalty

Most companies will intentionally avoid doing layoffs and only do them in these large batches when there are financial necessary (like the tech sector layoffs we saw recently). Only "shitty" companies lay off people randomly to balance/adjust the books
