Bribery on few occasions can help move ahead with the work. But, in broader perspective, it is unethical and builds a culture that will prohibit right and need people from getting their work done when these people cannot pay the bribe.
If a work or proposal or file is stuck and concerned person is not heeding, then higher authorities should be contacted and or other channels of communication should be applied to resolve the issue. It will set the benchmark and other people will also take lessons to refuse the practice of bribe. It can also be justified by the deontological approach of ethics as well as consequential approach to ethics. In the case of bribe, intention of offering a bribe is to facilitate the work by any means and it is not morally right. Further, the consequence of offering bribe, will also force other people to pay bribe to get the work done. Here, the intentions as well as the consequence of the action are morally wrong in the society. Hence, bribery should not be issued and it should be banned. It can be understood by the soul of Foreign Corrupt Practices Act.
