It would be tough to "briefly" state one's position on this, but here goes:
First: I think that Pennsylvania/Allegheny County should privatize PAT by selling it to the highest bidder. That would not only generate an immediate massive amount of capital for the state/county, but would take this money losing "ball and chain" off the books, thus, lightening the tax burden of the citizens. Additionally, since it would be privatized, PAT would generate income for the state/county in the form of taxes. Finally, it would most likely run more effeciently and most of our citizens would find riding the bus to work a more convenient and economical option than is currently available under the struggling system and management.
Second: When a union faces off against a business, there are always trade offs. Sometimes in the favor of the business, and sometimes in the favor of the union. When the union becomes more powerful than the business, and normal economics and ethical business practices are ignored in favor of satisfying a union, the power of the union becomes a detriment to all involved (Including the members of the Union over a given period of time.) due to a loss of productivity and profitability. (Google the death of the American Steel Industry or read the headlines about Ford and GM if you need more information about overly powerful unions vs corporations.) When a union faces off against a government entity such as PAT, the results can be disasterous. The reason for this is that PAT bears no responsibility to ensure a profit to its shareholders. They have an almost unlimited budget in the form of taxpayer dollars, and hold the monopoly for public transportation in our area & can therefore extort higher fares or cancel routes at a whim to meet the demands of the union.
I recall a time in Arizona when the Transit Authority threatened to go on strike for better retirement benefits and higher wages when the governor at the time stepped up to the plate and mandated that any person who failed to show up for work during the strike would have to re-apply for their job when they returned to work. When the strike proceeded, the state was without public transportation for exactly one day before the governor had hired truck drivers from all over the country (on a temporary basis) to drive busses. The strike lasted exactly 2 days with the loss of public transportation for only one of them. Several hundred union employees were replaced by non union employees who were willing to work for the prevailing wage and benefit package, fares did not increase and routes were not cut. I don't think Governor Rendell (A Union thug at heart) would have the fortitude to do that, but I think that someone with a responsibility to the taxpayers (shareholders) needs to step up to the plate to make sure that both sides of this conflict are represented.
In answer to the original question... The strike will probably result in either higher tax rates for wage earners and property owners or higher fares (or both). Other than that I will simply have a tougher time finding a parking place and there will be more traffic on route to work. Unfortunately, the people this will really affect (The riders) have no voice in this exchange.
