The term 'Stay-at-Home Worker' refers to a person who works from home, either as an employee or as a freelancer. The acronym UMP is often used to refer to this type of worker, which stands for 'Unemployed, Migrant, or Parent'. This type of job has become increasingly popular in recent years due to the rise of technology and the internet, allowing people to work remotely from their homes. Stay-at-home workers are often able to enjoy more flexible hours and a better work-life balance than those who work in traditional office settings.
