I've been in this situation before. My former boss liked "helping others" very much. If someone from other departments asked him for help, even if he didn't know what it was, he basically agreed. Of course, if a beautiful woman asks for help, it goes without saying that she agreed in an instant. Of course, he didn't do much of the next work. He shared it with us men and helped to deal with it. Then, after he finished, he took it back to "take credit". At that time, we all hated such behavior, but people had to bow their heads under the eaves. Who told us to have such a boss? At that time, we would also discuss it privately, but we know better that if we want to end this life as soon as possible, we must study hard and learn more, and then we can find a better platform before jumping ship. At present, even if it is annoying, you should help. If you are at ease, you should do more and learn more. At that time, capable people will work harder. Anyway, many skills won't overwhelm you.
