Unions are great and everyone should have one, but unfortunately there are some professions where unionisation is beyond the current imagination. Software engineers for example. They didn’t need one historically because wages were higher than many other professions, but that has changed over time due to an over supply of professionals. Its the kind of profession that encourages individuals to compete against each other for salary increases. I see many people doing unpaid overtime, partly because the field attracts people who work compulsively for reasons of professional pride.
