There is no fixed business arrangement, and the unit temporarily arranges personnel to do the work. Such personnel are called floating personnel.
The "mobility" here refers to the work with uncertain working time and place.
Generally, people who work in "mobile posts" have corresponding job categories. The specific work content must be determined according to the responsibilities and arrangements of the unit. For example: security department, maintenance department, training department, finance department and so on.
Generally speaking, migrant workers mean that others have clear tasks, and migrant workers have no clear tasks. When other posts have problems and need assistance, mobile personnel should be ready to provide help at any time.
