I am often asked whether working as a temporary employee looks bad on a resume. My answer is always the same: all periods of employment look good. Working in a temporary position can also allow you to develop new skills, audition for possible long-term positions within the company, and show future employers that you have a strong work ethic.
If you are having trouble finding a full-time position in your industry of choice, consider working for a temporary agency in areas that will strengthen your primary skill set and teach you additional skills. Experience in the work place is very important to employers and having diverse abilities will make you even more competitive.
