In a fast food, who is superior a management trainee or a supervisor?

Question

whats the difference between their work?

Answer 1

The trainee is usually a higher level, but I would caution as to using the word "superior."  As trainee you have to learn everything from cleaning floors to accounting and the supervisor is right smack in the middle of these and you could learn alot from them and the staff.  In any job you always want to be careful who you lean or step on while you climb up; you may need them to keep you from falling down later on.
