Malice, Ill Will
Someone with bad energy is someone who has evil intent, malice, or ill will. Hopefully you don't have too much 悪気.
The reading itself has a lot of 悪気 with all the exceptions it has. The 悪 part is read like 悪い. Then, 気 is rendaku'd. What an evil reading. Just think "what's the most evil reading I can come up with?" when you see this word. Then you should hopefully be able to read it.
I know you don't have any evil intent, but please understand that we could get hurt if you say something like that.
I didn't do it out of malice, but I'm really sorry that I made you feel that way.
By the way, how did you get the job without any experience in the first place? No offense, of course.
