Is there any advice what one should do in the following situation? I am unemployed in Finland. In Finnish law, if one provides you a job and you decline it, you won't get an unemployment benefit. But now a company that provides a really small salary and has a bad reputation offers me a job via https://kokeile.tyomarkkinatori.fi/Etusivu . I hate to take the job but I'm not willing to live some months without any payment. The job is about selling a product in telephone and my education is on a complete different field.
So, let us clarify the question. Assuming that you are correct on the matter of law, you have three options.
The first is to work for little pay, at a company with a bad reputation, doing something that's not in your field. Further, it's a job that's generally quite emotionally draining. (You spend your day calling up people who don't want to be called, and trying to convincing them to spend money on something that they generally won't want or need. People will react poorly to this. It is likely to be emotionally draining for you.) The issue here is that it's a lousy experience, not much money, and it'll make it harder for you to gather together the resources to find a real job.
The second is to accept that this company, by their offer, has deprived you of unemployment benefits, and push as hard as you can on trying to find a real job that is in your field as fast as possible, in the hopes of getting said real job before your money runs out. The obvious issue here is that you won't be getting any income in the meantime. If it takes too long for you to get a job, and you don't have the cash reserves to support it, you could be in real trouble. This one's going to depend on how bad the job market for your type is where you are, and how much money you have available in your emergency fund to cover situations like this.
The third is to try to split the difference. Being underpaid by a bad company to make sales calls is rough work, emotionally speaking. Is anyone hiring where you are? Is there an accessible gig economy? Is the military recruiting? Your situation has just been made materially worse, and you need to re-evaluate your available options. You may not be able to get the kind of job you want fast enough to handle your bills without unemployment, but there's a good chance that there's something out there that you could grab that would be better than the job you were offered. The issue here is that it splits the difference between the other options. On the one side, it might still take some times to get employed - you don't have an offer in hand right now. On the other side, once you do get hired, it won't be as good as the job you want, and you'll probably have to keep looking.
So, first, be sure that you're understanding the law correctly. If you are? You have three options to consider, all bad. Discard the ones you simply cannot accept, and see if there are any left. If not, lower your standards, and do it again. Pick the option that is least bad for your particular situation.
Under this system, what happens if you can't do the job?
This mandatory employment strategy is going to lead to many people being matched to work they cannot actually do. What happens to people who cannot actually do the job assigned? Do you get your unemployment benefits back if you are terminated for a lack of relevant skill?
If you can get them back, show up, accept that you will probably fail (as that is what happens to most people who try telemarketing), fail, and then get back to the rest of your life. You never need to list this job on your resume either.
