Wis. Admin. Code DWD § 133.01
The purpose of this chapter is to recognize that the employment relationship between a temporary help employer and an employee is, in limited circumstances, unlike that of other employment relationships. An employee of a temporary help employer commonly performs multiple assignments for one or more client companies. An assignment may end with little or no advance notice. While the employer and employee may intend to continue the employment relationship, the employer may not immediately be able to provide a new assignment to the employee. This chapter establishes standards for determining whether the employment relationship continues or is terminated for the purpose of unemployment insurance benefit eligibility.
