I see employment relationships mostly the same way
Apparently they did not.
At the end of the day, the people working at the company are the ones who are doing the work, and who have control of the means of production. The ex-admin's bosses probably thought they were the important ones, and that this worker was a replacable cog, but they found out the hard way that this was not the case.
I worked at a Fortune 100 investment bank where this happened. Everyone knew layoffs were coming. One week after layoffs came, a digital "bomb" went off wrecking many servers. So security went through, trying to find evidence (nothing incriminating from what I heard, although they had a strong suspect) and also looking for more bombs. They missed out on finding and defusing one, because another one went off a month later.
The view from the pinnacle, people counting the dividends on the checks that they inherited is that they're the job creators, and everyone else is dispensable. This company just found out that is not the case.
