I will try and write as clear as possible.
Here you go to trade school for 3 years to be a logger. 1) 20% practical. 2) 40%. 3) 55-70% practical. After that you work a year and then do quality test. Hopefully you are a logger then.
The schools here has wide trainings, most machines as harvester, cranes, log wagons, chainsaw, planting stuff. They get to test all, and learn. There is a 4 year period of work and same tests if you do not want to go to school.
Most students have work after finished study's.
This is an extensive education, with everything regarding the industry is represented the first year.
There is a multiple of laws regarding work hours, I am not familiar with all, but i can find out if you like. To remember all of these are for the safety of loggers and property's. In general for loggers it is 35 hours/week then 2 day rest. These rules can be bent a bit, like if you work 6-7 days you get 3-4 days rest. But no more than 45 hour a month, or 8 hours/day. All safety equipment available is worn (no exceptions), the employer is the one to enforce this is done. There is checks regularly, and those who do not use the safety gear is sent home. As are the ones who are careless/dangerous.
I can look in to these rules better as well if you like.
Anyone here can bye a saw, but the logging company's, as well as the forrest owners are bound by law to use certified loggers or do it themself.
Some wood company's even specify what bar oil to use, all loggers are using Aspen I doubt anything else is approved.
Since the hurricane here in south Sweden, there has been a lot of Hillbilly's in the woods, and the controls are hard. If you are under 18 and have less than 3 years experience as logger you are not let loose in the woods with fallen trees.
There has been a few that had "cheep labor" to go beside the harvester, all has been sent home, or hurt.
there has fallen a lot of wood here. About 6 years total harvest, fell down in 30 hours.
There is a lot to write on this topic, ask and I will do my best to get the answers.
