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 work in return for payment, which may be in the form of an hourly wage, by piecework or an annual salary, depending on the type of work an employee does or which sector she or he is working in.

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.

A salary is a form of periodic payment from an employer to an employee, which may be specified in an employment contract.

It is contrasted with piece wages, where each job, hour or other unit is paid separately, rather than on a periodic basis.

A part-time contract is a form of employment that carries fewer hours per week than a full-time job.

They work in shifts but remain while off duty and during annual leave.

The shifts are often rotational.

Workers are considered to be part-time if they commonly work fewer than 30 hours per week.

According to the International Labour Organization, the number of part-time workers has increased from one-fourth to a half in the past 20 years in most developed countries, excluding the United States.

There are many reasons for working part-time, including the desire to do so, having one's hours cut back by an employer and being unable to find a full-time job.

The International Labour Organisation Convention 175 requires that part-time workers be treated no less favourably than full-time workers.

Full-time employment is employment in which a person works a minimum number of hours defined as such by his/her employer.

Full-time employment often comes with benefits that are not typically offered to part-time, temporary, or flexible workers, such as annual leave, sickleave, and health insurance.

Part-time jobs are mistakenly thought by some to not be careers.

However, legislation exists to stop employers from discriminating against part-time workers so this should not be a factor when making decisions on career advancement.

They generally pay more than part-time jobs per hour, and this is similarly discriminatory if the pay decision is based on part-time status as a primary factor.

A person's job is their role in society.

A job is an activity, often regular and performed in exchange for payment.

Many people have multiple jobs (e.g., parent, homemaker, and employee).

A person can begin a job by becoming an employee, volunteering, starting a business, or becoming a parent.

The duration of a job may range from an hour (e.g., odd jobs) to a lifetime (e.g., judges).
