I approached my boss with this information. Expecting to get my first pat on the back since starting to work there a month prior, he said, "Well, just add that domain to our whitelist so she can get her mail." I couldn't believe it. I said, "But sir, not only is the company a spammer but they are taking money from this woman every month, she just doesn't know any better. It's someone taking advantage of an elderly woman -- we have to tell her!" He disagreed and said he didn't want to get in the middle of it. I don't know why, I didn't ask. He was the kind of person that is always right just because they are in charge. In retrospect, if I knew I was going to quit I would have told that woman everything. I hated the fact that someone was taking advantage of her. I was just scared of losing my job.
I was hired initially under a probationary period, which received a lower wage. Eventually, my probationary period expired. My boss let me know that he was extending it because he wanted more time to evaluate me (aka, I am going to keep you around on the cheap for awhile longer). I was fed up and promptly turned in my resignation. I came in a few weeks later to pick up may last paycheck and he told me he had to hire two people to replace me. I walked out of there with a smile about that at least.
Even being young and naive I was still able to spot the red flags all over that place. It has been something I have taken with me as my career has progressed. Having a bad manager early on made me really appreciate good management instead of taking it for granted.
