SMA is an appropriate way to maintain stable account value and minimize unnecessary accounts funding.

Likurg_2 [28]

The statement, according to the erosion model of an organizational commitment, the employee with the fewest emotional bonds is the most likely to quit, is true.

The erosion model explains that an organization's employee who have less or fewer emotional bonds tend to quit the organization because they do not feel or get involved in the organization, or they don't feel any attachment to it.

Here the social influence model states that suppose when two employees are closely related or have good terms, so if one of them quits their work, then the other one is more likely to follow them and leave the organization.

Hence, the erosion model suggests that employees with fewer bonds will be most likely to quit the organization.
