Not hard?

I rather suspect you have never installed let alone retro fitted a cage. EMF leaks everywhere, replace all windows with metaled glass, all doors need to be backed up, any vents need mesh, plastic pipes etc etc etc.

It's a nightmare which is why emf shielded buildings are usually built to spec by specialists.

It's worse than that for a company.

Most employees do not want to work for a company on a down swing. Most good employees can get a job elsewhere.

The result of a round of layoffs is the company dumps the people it wants and then it's better people leave of their own accord.

Downward spiral is then begun and very difficult to escape. Layoffs are a strong signal that a company is finished. It might take time but very rarely are they a prelude to a turnaround.

The only way to turn around a company is to fire management senior and junior. But that is almost never the solution taken.

Which company are you employed by? I'd like to know so that I do not bother to interview there?

Just a side note. As a manager there is not a single thing you can do that directly contributes to your perceived effectiveness. The perception of your teams' progress is the measure of your performance.

So stop whining about certain people and concentrate on making it as easy as possible for your team to succeed. In most companies that means clearing the road not driving the bus.
