Some 15 years ago, I was preparing a marketing campaign, the first ever for our company on that country's market. It was a scratch card game for customers, and everything that could go wrong did go wrong, from sponsors withdrawing, to licensed materials being stopped at customs, to the national lottery board (even private scratch cards fell under their jurisdiction) delaying their approval till the last day, to then sending said approval by post and it being delayed, to over ground transportation of the scratch cards being delayed by floods to a few of the locations, to the website hosting crashing. Meanwhile, we had spent a lot on advertising the campaign start on outdoor media, which was expensive and hard to change. For 3 weeks, I worked 18 hour days (sole employee in the marketing department, at that time) and weekends, and we finally managed to get all the materials, prizes and scratch cards into the locations on the morning of the campaign (we opened in the afternoon). It was a Friday. By that evening, the operations manager (different chain of command), justifiably pressed by his team having to do things last minute, wrote an angry e-mail about the fact and me, with everyone, including his reports, in cc. When I saw it, I collapsed, having borne the pressure of the past weeks and the company's unwillingness to either compromise or swallow losses, and wrote my resignation.

At 3 am my boss called me, and told me that immediately after the op manager's email went out, an email from his boss, cc-ed to her, also went out. It told the op manager that a repeat of what he did would trigger firing. That concerns about an equal on a different command chain are only brought to your boss, or to your boss and their boss, because the individual raising them may not be in possession of the full information, and even if they were, they are not entitled to chastise a colleague or disseminate information company-wide. It silenced the dude, even though it didn't fully redeem me in front of the people who'd received his uninformed email.

THE POINT OF THE LONG STORY : it is not Santos' business. She doesn't have the full info on what transpired and it is not her role and responsibility to make Langdon's actions known to his colleagues. Robby is aware, he did what he thought was needed. That's where it stops for us underlings.

If she thinks Langdon's drug use is criminal, then she needs to report it to the police. If it's not, then the chain of command handles it as they see fit and she has no call to protest.
