P&A,
Are you kidding?
It's not a job guarantee, it is indentured servitude.
Lets not beat around the bush here, if you have up to $80k of your own for a type rating you can be free of all of this.
If you don't you are asking a potential or current employer to invest hugely in YOUR career with no guarantee you will stick around. That's what the bond is for, it's return on investment. You are both getting something out of this, it's just that the operator is also financing a huge cost as well.
You are an example of the reason they exist. As GG pointed out earlier on, it hurts a company. Even to a big operator $80k per pilot is a huge amount of money.
HeliMutt also asked a question about why not give type ratings for current staff. Simple answer is that you're then paying for 2 type ratings, one for your current pilot to change types and one to hire a new guy to back fill that newly opened slot. It's nothing personal, it's just cheaper that way.
