Living in a country with strong workers rights, this is not how pensions work. The pensions people receive every month are literally paid by the taxes which are collected from everybody and every company during that month. Pensions are not saved money from companies you worked for, but money coming from the economy at the time of your retirement. It’s a common misconception that the state has a big pile of pension money sitting somewhere that you then get your pension from. That’s just not how it works in reality. Another difference from pensions to receiving money from a company just by owning parts of it, is also that you don’t continue to be on a company’s paycheck when you quit. You need to reach a certain age to receive money and you get that money from the state, not the companies you worked for. That’s how pensions work.
