Musk is now working out of Twitter headquarters, thanks employees for long hours

They almost certainly dont spend their time bragging about how they sleep on the floor.

[Steve] pointed out to [the CEO] that what he was watching was that his entire company had bought into the “culture of working late” – but not because they had work to do, or it was making them more competitive or generating more revenue, but because the CEO said it was what mattered. Every evening the VPs were waiting for the CEO to leave, and then when the VPs left everyone else would go home. Long hours don’t necessarily mean success. There are times when all-nighters are necessary (early days of a startup, on a project deadline) but good management is knowing when it is needed and when it is just theater.
