I like and support the idea, but that might bring some sort of extra work if it's to be used in salary payment, and some times it could also cost a company to pay more or less depending on the current Bitcoin price[..]
That's true of course. There are already platforms taking away the "hard work" in the salary payment mechanisms, like Bitwage. Of course for a fee (paid by the recipient of the salary). The OP also assumes an evolution towards a more stable price.
Volatility is already lowering but not enough for a widespread salary payment. We should stay for at least a year under 1.5%, maximum 2% (30 day average volatility) for that, and currently we're just above 3% (in 2023 the record low was recorded with 0,77%). Above all these panic dumps like in early August, but also FOMO phases like in early 2024 from time to time increase the value still a bit. Guessing from the chart, I estimate in the next crypto winter or early bull (maybe 2025 or 26) these conditions could become true.

Bitcoin Volatility IndexA singular currency can really affect the way people pay for job done because it will give everyone the same sense of value of money.
Exactly that. In some countries, the USD already has this function (for example, in South America), and in others the Euro (Eastern Europe). But Bitcoin has the potential to really unify this "sense of value".
I think one of the very major things affecting the different amount of salaries paid to different individuals doing the same kind of job in different countries is based on the economic level in that country the lifestyle and cost of living.
Yes, there are of course some more differences impacting in salaries than just the education level.
For example, a programmer in a country like India may pay less for housing (rent/buying a house) than one in the US, and that lowers the minimum value they're going to accept for their work. However, rent prices at least in the bigger cities are also "globalizing" gradually, and this could become even more pronounced if Bitcoin becomes a truly global currency (imagine real estate websites showing the prices in
BTC). This has of course also potentially negative consequence as it could lead to housing bubbles but in general this would be limited mostly to very attractive areas.
