The probability of recovering something is related to the legal environment, the determination of wanting to recover and other specific of the situation. If this company does any business out of Bulgaria there may be various levers to push there. The situation may also change going forward so at least documenting the situation and the efforts may end up being able to recover something in the future. Given that Bulgaria is in the EU it seems at least worthwhile to try. Sometimes the legal environment may actually limit your ability to recovery debt (e.g. bankruptcy) so having no rule-of-law can be an advantage.

At any rate, future employability prospects should not be a factor in going after unpaid wages.
