My understanding is that all service centers in Sweden are still servicing cars so at the very least a decent % of Tesla employees are not on strike while media makes it seem like most service technicians at Tesla are on strike.

That’s not the same as a union vote. It’s also not particularly surprising that non-union workers would not strike… since they’re not in a union. The whole point of this action is to give those workers collective bargaining leverage — the power to strike, effectively.
