Final answer:
A temporary employee may be entitled to retroactive benefits under the customer's collective bargaining agreement if they are hired at the end of their temporary assignment.
Step-by-step explanation:
When a temporary employee is hired by the customer at the end of their temporary-to-hire assignment, they may be entitled to benefits under the customer's collective bargaining agreement retroactive to the beginning of the assignment.
For example, if a temporary employee started their assignment on January 1 and was hired as a permanent employee on March 31, they may be eligible for benefits starting from January 1.
However, it is important to note that the specific entitlement to benefits and retroactive coverage will depend on the terms of the collective bargaining agreement and any applicable employment law.
