Dear Friend,
To decide on cases with legal consequences, the facts must be specific. Otherwise, the many answers received could be misleading, confusing, or worthless, despite the sincere contributions of friends and well-wishers. Moreover, these matters can only be commented upon based on agreed-upon conditions. It would also serve as a good case study if the fundamental agreement is known.
A general law dictates that not all agreements are valid if they are one-sided (lopsided). Additionally, only agreements not void in the eyes of the law can be enforced. Though I am not a lawyer, my understanding is that a one-sided agreement like a service bond is not valid or enforceable. The term "bond" itself is disputable. It is more appropriately termed a service agreement and is acceptable. A company may rightfully seek compensation for the investment made in developing an individual to serve for a mutually agreed-upon period in said company. Otherwise, in all scenarios, no party should have an overbearing right over the other, and none should be forced to waive their valid rights, including that of separation.
Perhaps some of our HR friends with law degrees can facilitate discussions by referencing the latest judgments on these matters.
