I listen to positive subliminal affirmations in the background of my calls at work. I work at a call center and I do this so I don't go crazy. Nobody knows.
What would happen if you get caught?
The company keeps a record of the scripts used in the background and I would be fired.
You are being paid to take calls at the call center, not listen to distractions. Focus on the job at hand or the company will find out and fire you.
I'm a professional, I know my job and I'm capable of multitasking.
I think you should talk to your boss. You can tell him how helpful the affirmations are to your job performance, and if he agrees you won't get in trouble.
