Fellow Romanian here, a person very close to me died of heart-failure in the middle of the street in downtown Bucharest 10+ years ago, not a block away from her employer's HQs at the time. She was in her early 40s, her employer was BCR (the bank that had just been acquired by Erste), and said close person had had a few fights with the new Austrian rulers to be, she was part of the bank's trade-union body, she didn't want her colleagues' jobs to go away after the purchase. The jobs did go away after the purchase, in droves.
A person even closer to me used to work for OMV immediately after they had purchased Petrom (our former State-run oil company). The stories I could hear back then could fill many pages, I still remember seeing the papers with hundreds of people's names on them, people who were supposed to be laid off the following days. And that was just from one company division. To say nothing of the fact that the Austrians had no oil drilling operations, no oil drilling specialists, nothing of the sorts, while Petrom had been in the oil drilling business for decades. Or how OMV had (I think it still has) as its major shareholder the Austrian State, so in fact we managed to sell our oil state company to basically another state.
My far relatives (but still the same last name) drilled oil in Romania before you could even call it really drilling, it was more like bucketing from what I was told. Maybe it was a bit exaggerated though the job was probably quite dangerous anyway as my relative almost burned to death. He was really lucky to survive with the burns he had - almost his whole skin was gone. The positive thing was, he grew a continuous layer of new skin and until his death looked very young.
It doesn't seem Romania is drilling much these days, more like refining imported crude oil before exporting the products. Judging from what was left of a different communist regime the last 30 years haven't been easy but most people seem to be much, much better off now than before the fall of the iron curtain probably also compared to the general QoL development in the world, I haven't looked up any statistics but it definitely seems like it. The quality standards now are much higher in every respect, the work in a factory is much safer for the workers. You are usually looking at many years of retirement even when you generally retire later where I hear stories about people from factories dying quite early probably because of the working conditions, many small injuries over the lifetime, fumes, dirt, smoking everywhere and all the time etc. If you get injured at work in Germany and haven't done anything against the protocols, it is a big problem for the company - you will be compensated usually very well for your trouble. Companies try to avoid injuries as well as they can in my experience on seeing the shop floors of a steel foundry, where safety really matters, else you are likely to get hurt fatally.
That said, no corporation is always doing the smart thing from the business or management perspective. There is usually internal politics, management strategies and more involved. There are also more and less competent people at every position. Maybe OMV should have kept some of the specialists and maybe educate them about the modern technology and methods. Generally the previous regimes were not very efficient with personnel and other resources so it is really hard to say what OMV should have really done.
