Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.

Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.

Employment is a relationship between two parties, usually based on a contract where work is paid for, where one party, which may be a corporation, for profit, not-for-profit organization, co-operative or other entity is the employer and the other is the employee.

Employees in some fields or sectors may receive gratuities, bonus payment or stock options.

In some types of employment, employees may receive benefits in addition to payment.

Benefits can include health insurance, housing, disability insurance or use of a gym.

Employment is typically governed by employment laws or regulations or legal contracts.
