Is this a trick to not given redundancy pay?

My MIL (for lack of a better word) has been told she is being made redundant and could either get paid for redundancy or apply for another job within her company.

My boyfriend told her that it's a way to trick her into quitting so they don't have to pay her out. Is this likely?

Edit: sorry for the typo in the title

Edit2: this was my boyfriend's theory guys, not mine 😭. He is too busy to give an explanation
