Sophia knows that her company will not be able to offer employees an annual bonus at the end of a poor sales year. Over the past ten years, the company has paid an annual bonus every year, so she is certain employees will be disappointed.

Thus, when the employees hear that there is not a bonus, they are relieved, as this is better than layoffs. Which commonly used heuristic is Sophia utilizing?
