When I started writing this answer it was not clear in what context you were referring to major and minor, so I have taken the opportunity to answer from the point of view of one of my greatest passions:
Tonal music can be based around "Major" keys and "Minor" keys.
A piece composed e.g. in C Major will be based on a diatonic scale formed by: C, D, E, F, G, A, B (a sequence played by pressing the 7 adjacent white keys starting with a C and ignoring all the black keys.
On the other hand a piece composed in C Minor will be based on a scale formed by: C - D - E flat - F - G - A flat - B flat ( C, D, E♭, F, G, A♭, B♭. ) which includes 3 black keys within the C Minor scale.
Here is an example of a stunning C Major piece - The Fugue from the Toccata Adagio & Fugue in C Major ( BWV564 )
And now an example of a beautifully crafted sequence of variations in C Minor - The 1st movement from the Passacaglia & Fugue in C Minor ( BWV582 )
(Both pieces composed by Johann Sebastian Bach and played by Hans-Andre Stamme).

A major is what you spend a large percent of your focus on, a minor requires between like 4-6 classes. As for finding a job, a lot of people dont even find jobs in the area they majored or minored in. A minor is not really sufficient to be well versed in a subject. For example, I minored in religion, it was only a few classes and I certainly can't do anything with it. Regardless, I wouldnt worry too much about it. Most jobs tend to be pretty flexible and majors and minors in particular subjects help, but they generally arent required. Having something tangentially related will usually do.
If you are in university, a "major" will be the main area of studying you are doing. A "minor" is a secondary area which you wish to incorporate...For example, if you want to study for your Bachelor of Business (in Australia), you may decide to elect, Accounting as your major (you end up doing the core units which makes up the accounting course) and you select Marketing as your minor. (you end up doing at least 5 units of the base units). Once successfully completed the course, you graduate with a Bachelor of Business degree but majoring in Accounts.
if you mean in school the the major is the feild that you put the most study into, the major is the higher degree the minor can be something you just want to study for fun.
yeah i am. i posted the question. so would it also be like if there is no job in the major u can try your minor and find a job on that?
yep that would be one reson to have a minor or you can double major but that can be a lot of work
o ok thanks
