The issue comes with what you mean by temporary job.
We have part-time employment, which is about 30 hours or less per week.
We have full-time employment, which is generally 32 or more hours per week
We have seasonal / temporary employment which can be either full-time or part-time, but it only last for a certain duration of time.
So, if you were hired as a temporary employee, you might work over the Christmas holiday season. It would last for two or three months, but you might work full-time for those months.
Students working in Fast Food typically are hired for part-time employment so they can work and go to school.
Steady, or permanent employment would signify you were working at a job which does not have any set duration for the employment. You can be a permanent full-time employee or a permanent part-time employee.
