I'm not sure why this question is getting such a harsh response, perhaps as it was phrased slightly dramatically.

If the many facets of the business we as consumers witness and read about as being stretched, over worked or under resourced are there for us to see why is it inconceivable the same impacts are occurring within the maintenance & engineering dept where the traveling public don't see? Were they immune from layoffs, and not prone to covid or fatigue themselves? This is not to say it's systematic of course, but looking at how they've handled much else I doubt they're operating as resiliently as they were pre covid. Does this make them less safe? We'll I can't see how it wouldn't. Are they therefore less safe than other operators, I'd say almost certainly not
