Depending on the real and full extent of the story, I doubt I would want to work in such a place. I'm not real fond of someone meddling with my personal belongings in my office. I'm also a little perplexed at the rationale behind taking someone "off-service" (because their abilities were in question? to punish them for something?) and putting them on frozens where consultation is typically more difficult to obtain and decisions lead to immediate consequences.
As for consultations, one really doesn't get to say they consulted about a case without actually doing so. And if you do so, it only counts if you document that you did so in that report. I've heard of cases where a junior showed a case to a senior before signing out (inaccurately as it seems to be) and the senior claimed they were only shown certain slides or certain fields on certain slides (which of course aren't the relevant slides or areas for the "mistake"), effectively trying to throw the junior under the bus. It's also quite possible for the senior to just be wrong -- nothing says a newbie board certified pathologist is automatically wrong while an oldie is right. Signing something out because you can't rapidly get a consult isn't likely to get you off the hook. I -have- heard of people who sign something out as pending consultation or somesuch, which apparently was simply a way to shorten calculated turnaround times; they amended the report with the final later.
Edited to add: As for mistakes, as one of our contracted teachers liked to come in and say, the acceptable error rate for a pathologist is zero. Everyone knows that humans are prone to errors of all sorts, but the level of tolerance of them in pathology is excruciatingly low. Private practices can generally terminate someone more easily than other employers, but it depends on the contract, what they say they're firing you for, and applicable law.
