> you’ll notice that Mr X never promised to have the data. He instead said he lacked the data.

I don't know what the actual situation was, but what the parent typed seemed to indicate Mr X was implying he could provide his data later (but based on past experience, never will):

> "I don't have the data right now" — and it will never be provided

I'm all for people working a reasonable number of hours and getting plenty of sleep. But if you are steering major decisions, you need to be able to substantiate up your reasoning. Being overworked is not going to make your judgment better so everyone acting on your questionable directions without confirming data is made all the more risky.

I hope your own situation has worked out.

I changed teams and went on a meditation retreat. Things are much better.

Your larger point is correct up until the point where the decision is “I, Mr. X am not going to take on that additional work.” Until Mr. X exercises the autonomy to say “no”, he will always be overwhelmed and struggle to think and speak clearly. Until others trust him when he claims something is hard and are willing to take no for an answer, their distrust will make him untrustworthy.

It is a vicious cycle.

If somebody's overworked, then their boss is not doing their job well and should be complained to.
