Unless you are a salaried employee who is expected to work as many hours as necessary to complete your work, you may have opportunities to work overtime at your current job to earn additional income.

One of the best perks of working overtime is that you're usually eligible to receive more pay per hour for hours over 40 per week — sometimes as much as time and a half or double time. That can add up to a lot of additional income in just a short amount of time.

Be aware of the overtime commitments that your company may require, however. Some companies expect you to commit to working overtime for a set period, even six months or a year, before they'll allow you to sign on.

And the time required may be open-ended, so that you're getting home at 6:30 P.M. one day and 8:00 P.M. the next. Before accepting this opportunity for additional income, be sure you're clear on exactly what's involved.
