No it's not. Equal pay for equal work has been a law that has been in place for half a century at least. A company could EASILY be sued if they were paying two people, of the SAME seniority doing the EXACT SAME job, with the SAME hours and the SAME level of training - a different salary. But this is the problem. When feminists bring up this argument, they are always comparing apples to oranges. They fail to take into consideration the fact that men tend to take on much more dangerous types of work. They tend to work longer hours on average and tend to be motivated to take on higher levels of skills training. For example, if I were a feminist, I could point out the fact that at my place of work, I do the same job as everyone else there and even work harder than most of them but I'm paid less = not fair right? Wrong. The reason I'm paid less is because I haven't been there as long. In my field, there is a pay grid and I'm at the bottom right now. So even if I work harder and do the same work, I am paid less. It's not that this is an injustice - it's simply a reality. One day I will be at the top of the pay scale too.
