The way I did is one way. I don't think the way our business does things is that unique. I work as phone tech. rep. in the customer service department of about a 200 million dollar a year company. There are eight other people who have the same job description I do. Each year at review time each department gets budgeted an amount of money to give out in raises on a merit basis. Last year I was awarded the largest raise in our department because despite being their the least amount of time, I was still making entry level pay for doing the same work and then some as everyone else and I had the documented the data to prove it.
THAT is how you negotiate a raise. It's pretty straight forward. Your job description says we'll pay you x for doing y. If you demonstrate you're doing y+, there's your grounds for a raise and you plead your case. If they're any type of company worth working for you'll probably get it. I did. It's not at all uncommon for higher skilled positions. You may have seen job descriptions for job openings that say something like 'pay dependent on experience'. Admittedly though you don't see much of that in the low skill, low paying jobs for a couple reasons. One is a lack of leverage on the part of the employee. There are just too many other people out there that can do what the company needs done for the same price that they don't need to budge to much on their low pay positions and if you bring so much more to the table you should be trying for something else anyway. The other is to FAQ's point; at some point libs have to start holding individuals accountable. That which you don't acknowledge will not change and libs don't acknowledge that all these poor people making sub living wages are where they are because the make bad decisions. That's where the problem solving has to start. If the goal is to get these people more money, you don't start by petitioning the government, or striking, or bellyaching about greedy bosses. You engage in critical, objective introspection and first ask 'What am I doing to contribute to how much income I bring in.'?
Ok, but the whole thing goes to hades, if it is not a company worth working for, or as you spoke of greedy bosses, where as what has been a problem today is this trending that got started among companies and these bosses in this new way of thinking where companies began looking out into the deep blue sea of employee's, yet with a new greed and a lust in their eyes, but it wasn't a lust for a good employee; no but rather in the opposite, where as they wanted an employee who could be exploited and was dumbed down to a level in which could be exploited by them, and they got what they wanted because of the quickly changing landscape of major manufacturing companies taking advantage of Nafta, leaving hundreds of thousands floating out there to be taken in by others regardless of their skill sets (fish out of water), and then miss-treated sadly enough. It's all about leverage as you say, and the companies got a huge leverage over the American employee, and they showed what they could do with that leverage once they got it, and it wasn't pretty in many ways. Now the government decided that it would kick in and save these employee's once they (the employee's) became distraught and angry or confused badly over the situation, so they (the government) began trying to level the playing field, and they began giving great benefits or incentives for an employee to sit on their butts in resistance of the problems being faced by them, but what this caused was a huge dependency by the thousands on government, so the government becoming a union boss as it did, and therefore sidelining thousand's like it did wasn't the right answer either in the situation. What the government should have done, is become a mediator between worker and company but not a fix all in the situation, because that is how we got to where we are at today in all of this.
