"Companies need to stop being cheap and shell out money to bring on seasonal CSR employees to help or something. I just don't get it."
LOL
You think they don't? Lots of money is invested into training new agents all the time. The problem is you'll be lucky to have 5 people stay after a 20+ class when training is over. Even luckier if more than 2 stay after the first year.
Do you think anyone actually wants to do a job like this long term with back to back calls of people blaming you for everything under the sun? A job where your livelihood depends on bonuses where a caller mad at the hold times, something an agent has zero control over, can make sure they don't get with a bad survey. It's not even Covid. When you underpay people, you get what you put in. Turn over is high because the amount of stress to pay is disproportional.
