Normally these ageeements are time limited to say 1-3 years and then needs to be renegotiated, this is when union requires some certain salary increases over the next agreement period and for that promise to not strike given that the employer hold up the agreement. Should the not come to a agreement during the negotiations, strikes are an option.

Found a quite good article about differences on the helmets (and some other firefighting techniques like fognails) in https://www.firehouse.com/safety-health/ppe/helmets/article/...

This fognail video was quite interesting also https://www.youtube.com/watch?v=Oe_V7aLyzM8

I guess one example is bikeshops providing air for bikes for free. But I agree, not many services provide things for free. I’m assuming gas stations see it as a way to draw in customers, many also have bathrooms for free.

Interesting, here in Sweden air is always free, however vaccums cost money (but way less stations have vaccums).

Yeah, more or less every manned gas station in Sweden has that.

Coop the store chain is owned by a cooperative association (https://en.wikipedia.org/wiki/Kooperativa_F%C3%B6rbundet) so would say it is legit still.

Avanza supports loaning out stocks depending on the account type, it is only available on Kapitalförsäkring because otherwise the stock is in your name (on Depå / ISK). Also you get paid a premium if they loan your stocks. It is described on https://www.avanza.se/konton-lan-prislista/konton/kapitalfor... and includes a section about the risk.

Not less efficient than just using electricity. At -20C you get 1:1 electricity to heat.
