It's just similar companies responding to the environment (market, covid, etc.) in a similar rational way.
And a bit of a herd mentality too, which is human nature. But that doesn't require collusion, it's just board members reading headlines.
There are plenty of companies still haven't done layoffs (Apple), or have even raised employee salary (Nintendo, Sega) to ensure that employees feel safe and continue to perform at high levels.
If anything, it's irrational behaviour. Herd mentality, prioritizing the short-term, fear-based, etc.
OTOH, if a company cannot offer WFH/remote now, then I'd say that's a strong signal of a money losing company that's in trouble. Hint: a lot more than you think, they just were able to coast on easy interest rates for so long.
At any rate, the Fed will eventually inflate the trampoline below this falling economy. The economic pain will be too much to bear, especially given how vulnerable Biden is for re-election.
Even if that wasn’t happening, public announcements like this signal copycat behavior is fine.
