Answer: Daily and weekly task requirements
Step-by-step explanation:
From the question, we are informed that Shelley has been hired as a marketing specialist at a large, international firm and that on Shelley's first day of work, she attends an orientation session.
The least likely to be addressed during Shelley's orientation program will be the daily and weekly task requirements. This is because this is really not important at the orientation.
There are other important things to talk about such as the organization Structure, company policies etc.
