I’d like to give the company the benefit of the doubt, but in my experience they don’t deserve it. They probably hired you at lower rate to get a steal. Remember, all businesses are in the game to make a profit otherwise they die, which is bad for you. At the same time, if you leave the company, they also loose. They have hiring costs and training costs invested in you and you have part of the company mind-share. They do not want to loose their investment in you.
If I was hiring you, I would bring you in as low as possible. Let’s say at 50k. If this your first professional job, you are probably use to making 10 to 15 dollars an hour. That is roughly 30k a year. They offer you 50k a year. That seems like a lot of money to you and you accept.
You graduate with a degree, yes you are worth more, but we started you out at 50k. We’ll give you a 10 percent raise. They will give you some line of crap about how a 10 percent raise is almost unheard of in the industry and it’s tough times! You can tell them it’s not enough and explain to them the average wage is 65k for your position and that you’ll cut them a deal and accept 70k. Because that’s how good you are. Or you can do what most people do and accept the 10 percent wage and feel all warm and fuzzy inside.
Are you willing to find another job? Your bargaining chip is you leaving. I’ve seen people ask for a raise and not get it. They leave company and come back a year later taking a higher position and making double their old salary.
