I didn't see him say that, but that's really not my point. I'm not commenting to criticize him. I'm offering the consulting survival advice, which I'm pretty sure is generally applicable to all contracting gigs: don't work late for clients unless you absolutely have to.
I consider calling someone's behavior a pathology to be criticism.
That's fair, but that's not how I meant it.
They were obviously not impressed that he missed a day of work, one of many. I'm not surprised they let him go.
Consultants are not employees. Consultants are allowed to take off days anytime. They're allowed to start work at anytime and end work at anytime.
If they got this pissed about it, my guess would be that the client called Pillar and complained. Pillar must have felt that the author not going into the office made them look bad.
