The rating system that Tesla's mechanics in Sweden are judged by seems to incentivize poor service. Troubleshooting is discouraged and pushing the car out the door in shortest time possible encouraged.^1

It's pretty much the opposite of what we did in a similar field of work. Getting things right on the production line, even at the cost at stopping it, usually saves money long term. I'd wager it's similar with car service, repeat visits eats unnecessary resources and makes customers dissatisfied.

There's a decent chance unionisation at Tesla Sweden would improve Tesla by improving the rating system used for wage negotiations.
