Bite the hand that feed

The idiom "Bite the hand that feeds you" is a common English expression that means to harm or betray someone who has been kind or helpful to you. It implies an act of ingratitude or unappreciation towards someone who has been supportive.
This idiom has its roots in the behavior of animals, particularly dogs, who sometimes bite the hand of the person who is feeding them. It is used metaphorically to describe situations where someone acts against their own best interests by harming the person or entity that has been providing for them.
Here are a few examples to help illustrate the usage of this idiom:
1. Example: Tim had always been supportive of his friend Jack, offering him advice and helping him in difficult times. However, when Tim faced a setback, Jack spread rumors about him to colleagues. In this situation, Jack bit the hand that fed him by betraying Tim's trust and harming their friendship.
2. Example: Sarah was hired by a prestigious company and was given several opportunities to grow her career. However, she started to slack off, missed deadlines, and showed a lack of commitment. Eventually, her employer had to let her go. Sarah bit the hand that fed her by not appreciating the opportunities given to her and not putting in the required effort.
3. Example: The government provided financial aid to a struggling business to help them stay afloat during tough times. However, instead of using the funds wisely, the business owner mismanaged the money and made poor decisions. The business eventually failed, and the owner was left with nothing. In this case, the business owner bit the hand that fed them by wasting the aid and not utilizing it effectively.
Overall, the idiom "Bite the hand that feeds you" serves as a reminder to appreciate and value the support and kindness of others, rather than taking it for granted or acting against their best interests.
