i've been lurking on this thread and i figured i'd give my 2 cents worth on the "big picture", so to speak.
a union will be effective only if it has a certain degree of parity with the company. this parity will be present only if the company is in a position to lose a lot if it does not deal with the union. for example, unions in banks and other large companies succeed because these companies already have considerable investments in assets and infrastructure (not to mention large loans which they have to repay), and they cannot afford to lose these investments, the income or their otherwise profitable business if the employees go on strike.
think san miguel beer as an example - if the employees go on strike, how long can the company endure? it might have inventory, but this won't last if the strike goes on and on. in the meantime, there are bills and loans to pay, equipment to maintain, raw materials deliveries have to be diverted to other warehouses (hence more bills to pay) because these can't get inside the factory, etc., etc., etc. - a long list of problems that crop up when business shuts down. the longer the strike goes on, damage is wrought on both sides (bec. the employees don't get paid either), so it's a question of who will blink first. either way, the union is negotiating from a position parity - more or less equal strength/position versus management, bec. it is in a position where it is forcing management to deal with it fair and square.
someone has posted that call centers are being opened in the philippines bec. the owners don't want to comply with US labor laws. assuming this to be true, then i wouldn't be surpised that a call center will close once its employees vote to form a union. compared to the large, established companies (banks, etc.), call centers don't have considerable investment in fixed assets, because actually, its major assets are the employees themselves who want to form a union. under this scenario, the owners probably won't hesitate to lose their investment and close shop. after all, they already did this when they stopped operating in the US and moved here, where their investment in fixed assets is considerably lesser.
having said all that, i think lytslpr's purpose in making this thread concerns the way the policies are being implemented. from what i gather, it's either not implemented, inconsistently implemented, or abusively implemented. if so, then the employees affected should file cases in the DOLE.
this, however, is a somewhat gray area in labor law. the DOLE is mostly concerned with the conditions of work, i.e., correct wages, hours of work, etc. issues on company policies, however, fall under what's known as "management prerogative" - the right to prescribe rules and regulations on the operation of the business. as long as these rules, regulations and policies are fair and reasonable, then the management prerogative is recognized and respected, even by the supreme court. for example, you are being transferred to another department where your skills are needed, and instead of an 8-5 workshift, you are going to be on the 2-10 shift, but there is no diminution in salary and benefits. if you refuse bec. you don't want to change shifts, you will be charged with insubordination and dismissed. in this situation, as long as the company can show that your transfer is necessary, then managment's prerogative in transferring you will be respected. another example is the banning of cellphones in the workplace - as long as there is a reasonable justification for this, then this policy will be upheld. this princple of management prerogative was established because the government cannot be expected to poke its nose into each and every decision that a company makes. if this were so, then every management decision will be contested, and you can imagine how many thousands of cases that will be filed on even the most minor management decision.
i think the bottom line is this - there may be strength in numbers if employees form a union, but it all boils down to a question of whether or not the owner of the business is willing to lose his investment (if he hasn't recovered it yet) if a union is formed. if the owner isn't willing, then it's a good bet that a union can succeed, but if he's willing to give it up, then the employees would lose their considerable income (compared to that of a minimum wage earner).
