Automatically check box once name selected from dropdown list in a userform

In my Userform that I have created, I have a dropdown box for the employee to select their name.
Once this happens the employee can then select 1 of 3 shifts for each day.
From the employees list there are 2/3 people who are part time.
Is it possible that when these 2/3 people select their own name that the part time box automatically becomes checked?
Once the part time box is checked it automatically selects the only shifts the Part timers can work.
Thank you for any help you may be able to give me.
