Take this opportunity to negotiate a raise. When you don't get paid what you deserve, you feel undervalued and resentful. Be direct and specific about your financial demands. Having a point of comparison will be helpful. When your employer realises how much people with similar skills and accomplishments earn, they'll be pressured to meet this standard. Are you dealing with someone who has a 'take it or leave it' attitude? Start looking for a better position. Better yet, think about starting up a business from your own home.
