The term poaching is common, but is a word that overemphasized the importance of the hirer.

There are 3 parties involved. The worker choosing to accept a better offer. The hiring company making a better offer. The previous employer offering unsatisfactory terms.

The term "poaching" suggests that the departing employee is being "stolen" or "taken" from their current employer, implying a sense of ownership over that individual. Employees are not property; they are individuals with the right to seek better opportunities and make their own career choices.
