How long would the man’s suggestion probably come into effect?

M：My suggestion to cut expenses is to reduce bonuses by 30% for the next 3 months.
W：But，Tom，those bonuses help motivate our sales staff， and well-motivated sales help bring in more new accounts for the company. They won’t like this，especially considering their vacation days were already cut a couple of days ago.
M：We’ll explain to them that it’s only a short-term measure. I think they will understand.
