Final answer:
Commissions are not always negotiable; it depends on the circumstances and parties involved.
Step-by-step explanation:
The statement that 'commissions are always negotiable' is False. While commissions can sometimes be negotiable, it ultimately depends on the specific circumstances and the parties involved. In many industries, the commission structure is pre-determined and non-negotiable, especially when it comes to sales positions. However, there may be instances where certain factors, such as experience, performance, or the rarity of a particular product or service, can influence negotiations on commission rates.
