Those who are sincere and faithful in the work assigned to them will not try to make such allegations. Such people will work accurately and produce results. As the author's post, some blame the tools they got when they go for a short-cut. Such allegations are often made due to inadequate work and irregularities in the work to be done, lack of knowledge on how to approach a problem, and lack of skill in dealing with problems that need to be resolved quickly.
No one will not raise such allegations if he is an expert in the field of work he has been given and ready to think over the problems to face.

I see some of the employees in the government department don't want to work for people if any complaint is made to their senior officer, nothing happens positive, rather their inclines to defend themselves. He does not care about the problem a customer may face.
