[Dustmen will go on strike because they think their salaries are too low]
Students often express their views in an over-certain manner, and are particularly fond of the "will" form, as in our example:

a) "The government made a mistake when they intervened

b) "Next year’s students will have less money to spend on
    entertainment"

c) "The criticism is so strong that the President will have
    to resign"
