there is no problem with the bonding. Why should you leave in the first place if you ewant to work?
you would only leave if an other company pays you better, and usually if this is the case is the new company that take over on your bond and there you are bonded again to the new company.
there is only one solution if we all want to make a good and decent living doing this job: DO NOT PAY TO WORK, DO NOT PAY FOR TYPE RATINGS, at the end of the day companies will need pilots anyway and if we are all united in this they will pay for everytuing as it was common procedure until 6 years ago.
And by the way there are still few companies that pay for everything.
More over on bonds, after the contracted years (3 or 5 or whatever) you get all your monies back plus interests if you deposited it, anyway the best solution is to bond via insurance companies or via banks without depositing the monies (so you can do it also if you do not have the monies) you just have to pay the services fees ( for example some offer 2% of total bond per year).
