Twitter is now having trouble paying some employees on time

The technical infrastructure at Twitter may prove more resilient than the business infrastructure. Payroll, accounting, and sales (ad sales in their case) count as "infrastructure" but not part of the technical setup. With a demoralized skeleton crew and key departments like payroll and HR apparently hollowed out Twitter will fall apart just as surely as it will from purely technical issues.

Arbitrarily firing/laying people off and failing to make payroll triggers regulatory and legal problems in the US, and I imagine even more so in European countries with stronger employment laws.

Yeah...when the paychecks don't show up, that's...superbad. I doubt that there's anyone still at Twitter who might be on the fence, but when the paychecks don't show up, that's god telling you to get another job, ASAP.

Twitter staff missed one paycheck and they get overdrawn and have to call their mortgage company?

Completely aside from any commentary on the behavior of Twitter management, please please everyone have your finances together with an emergency fund.

Take a hard look at lifestyle creep and be brutal. Especially when layoffs are expected for months!!

Yes unfortunate events could have drained emergency funds already for those mentioned in the article. Giving them that benefit of doubt, take it to mean one should either have more than one initially thinks or be beyond totally confident in one’s expected needs.
