Well, then there will probably be other steps. For example electricians unions blocking any work or maintenance on Tesla charging infrastructure.

The unions collective agreements in Sweden and pretty standardalized and include standard things like pension offsets etc. So not a big bruden for serious companies.

From a company/management point of view it is often something good in the end if in addition employees are union members (I’ve been in this situation myself as a manager in Swedish companies): Say you want to terminate someone, they will get union representation. There will be very little hassle and the process will go smoothly since everyone in the room knows the rules and when the employee gets upset their union representative can help them move forward without unnecessary hassel which would lead nowhere.
