Somebody hijacked my assignment instruction that I gave to my students. Without asking me for permission to use it in his class, he simply removes my name and replaces it with his name. Plagiarism in academia? It is quite rampant apparently. Most of the time, people might think that they need to give credit on journals articles, but they might forget that they should also give credit to the person of any material that they use like course instruction. What a heck, right! You might think it is unimportant but to this junior, screw you!
