Before you go work for a place that calls people to ask them to donate blood, please know that about 6 months in, you will be hounded by the supervisor for more appointments. You will have no control over if the donors answer at all, what kind of mood they are in, or if they even want to donate ever again.
You will be at fault and they will always point something out that you did wrong(didn’t resemble a robot in) such as taking an extra 3 seconds before sending the next call.
The people at the top are making bank while the call center agents are abused and don’t even make a living wage. They get told they are saving lives and then hounded for more appointments.
Reddit is flooded with blood donation schills and bots that gaslight you for saying anything bad about their industry. In reality, most people are angry that you won’t stop calling and some will curse and threaten.
I am not saying that you should not donate blood. I am a blood donor myself (inactive).
If you want to give them a reason why you won’t schedule, besides the fact that they give you a pin for donating loads of gallons of your life and health, you can also mention that you don’t like the way the call center agents and donors save lives so that upper management and up can make major bank.
