Continuing from my previous posting in response to your second rejoinder:

You then ask an interesting question. (I'm not sure that this belongs in the "Moving to Finland" category anymore, but anyway...)
Hank W. wrote:- Say some foreign student dude had moved to Helsinki for this one job from say Oulu, gone sign the contract on Monday and been cold-sholdered "we got no job, the project got cancelled"...and the ex-boss had told him he's already been replaced, he's said off his flat etc. as they wanted him to start ASAP.
- How about the 3 months unemployment quarantine?
- How about verbal contracts being binding?
- Whom to ask for information, as the unions won't help? And the unions won't help if you are not a member, and you're not some bogtrotter who just flew over from Oulu, but say you flew from Frankfurt and don't even speak Finnish.
I'll bet Daryl a pint of Guinness, my man's union will not help (student member).
I'll bet another one, if the job is still open a week its a discrimination case, a white man cannot get help for that.
So Daryl, want to take the challenge?

The question (if I have understood it correctly) includes various issues in labour law and the immigration system. These situations are not unprecedented. I have helped to tackle one or two problems of this kind.
My labour law analysis may be slightly dated, as the new Employment Contracts Act does not approach this matter in quite the same way as the previous law. However, the classical approach draws a distinction between a contract of employment (
työsopimus) and an employment relationship (
työsuhde). The contract of employment comes into being when a definite offer of employment has been firmly accepted. The employment relationship, on the other hand, begins when the work begins. If the arrangement is broken off after the contract of employment has been made, but before the employment relationship begins, then we have breach of contract, but we do not have dismissal.
The Employment Contracts Act is mainly about employment relationships, and its dismissal provisions, normalised damages etc. will not apply where no employment relationship existed. Instead, the case that you describe is purely a matter of tort law (i.e. the law of contracts).
The employer's side of the employment contract was a promise of work and, especially, of remuneration for that work. When the work and remuneration did not materialise, the employer broke that promise. The other party to the relationship, the employee, was entitled to rely on the promise that had been made. In expectation of that promise, and in order to perform his own side of the bargain, the employee gave up his job and moved to a new location.
The employee was specifically damaged by the employer's failure to keep his promise. This damage can also be quantified in terms of lost earnings, removal expenses etc.
This provides the elements for a civil lawsuit against the employer for recovery of these damages. This is not an action for unlawful dismissal per se.
Here endeth my general analysis.
Now to your specific points:
1. The waiting period for unemployment benefit applies to workers who become unemployed wilfully or through intentional default. It clearly does not apply in this case.
2. The contract of employment was binding. There are no requirements of form in contracts of employment, and an oral contract (I think that's what you really meant by "verbal") is just as binding as a written contract.
To the extent that issues arise here, they are issues of evidence, i.e. of what can be proved. These issues will be settled by examining the evidence indicating that a promise of employment was made, and indicating the details of that promise. The collective agreement covering the work in question is a relevant document at this point, as it establishes the legal minimum benefits that were promised to the employee.
In an extreme case the employer might try to pretend that no job offer was ever made. The court would then have to examine the details of the behaviour of both parties (communications between them, etc.) and seek the most plausible view of the situation as a whole.
In the case of a foreigner accepting an offer of work, there may also (depending on the circumstances) be a document submitted by the employer to the employment authorities specifying the terms and conditions of service. This document would have to exist if a special labour market assessment was requested (an application for a worker's residence permit or for an opinion that no such permit is required for the work in question). It should also exist if the employee falls into other, especially recently arrived, employee categories (particularly 3rd country nationals), even when no special labour market assessment was requested.
3. A union member would have an automatic right to free advice and assistance in a case of this kind. A non-union member would probably end up paying for this kind of help and bearing the financial risk of any ensuing lawsuit. This boils down to a type of insurance against the hazards of working life. It helps to be insured when things go wrong. Union membership provides this kind of insurance.
The uninsured non-member would have to find a competent legal advisor. This competence goes beyond mere legal skills - the advisor also needs to understand the industry in question and have the inside track on the employer (e.g. from the shop steward). Non-union legal advisors need to get up to speed, which takes time and inflates the legal bill.
Newly-arrived foreigners are in an especially difficult position when things go wrong at the start of the employment. My own union is (or at least it used to be) broadly aware of this, and will generally offer free advice, if not outright support to a foreigner working in an industry in which we are active. Part of the rationale for this is that we cannot tolerate this kind of misbehaviour from employers in our industry.
The problem is the same for all newcomers to the job market, but it is particularly difficult for foreigners. The immigration system includes some elements to protect certain classes of migrant worker from the worst excesses of the job market.
Interestingly, it offers no protective mechanism whatsoever for "returnees". This means that the "easier" immigration process (owing to racist regulations) may seriously backfire when some poor Canadian great great great grandson of a sonofabitch from Czarist Finland decides to drop everything and accept that dodgy job offer in the "old country". At least the prospective employer of M. Ahmad Aqbar from Muukalaistan has to jump through a few bureaucratic hoops in order to get his man. Hard to deny that there was any job offer when you've spent 3 months trying to persuade the authorities that you really need someone...
Your pint of Guinness is safe enough - I don't touch the stuff.
