Does the question also imply that none of the employees can be assigned to any of the two offices?

Employe 1 can be placed in two ways (either office A or B)
Employe 2 can be placed in two ways (either office A or B)
Employe 3 can be placed in two ways (either office A or B)

No of ways all three can be assigned. = 2*2*2=8
