> What do you mean by "monitor and control"? Should an employer not be able to see what their employees are doing at work?

I don't see any reason to get into a discussion about how much an employer should or shouldn't be able to monitor and control their employees. Some businesses are simply more trusting of their employees and allow a great deal of independence, while others aren't. Those that aren't will naturally face greater barriers to monitoring and controlling employees who are working remotely.

> What is an "excuse" for a layoff, exactly?

It's no secret that when the return-to-office movement began, many businesses used it as a means of achieving a headcount reduction. Employees who could not (or would not) return to the office were let go. Parting ways with difficult employees looks much better to investors than layoffs.
