That's actually a bit part of why unions have not traditionally been seen as necessary in tech. Employees had more leverage even without strength of numbers than many other jobs. Combined with the relatively high number of employers, the threat of an employee saying they'd just leave if they don't get better conditions was real.

Current economic conditions change that. Fewer companies are hiring, and AI makes it easier for a new employee to learn what's going on in your system. So the need to unionise grows.
