Re: salary with experience
For the purposes of placement on the pay scale, taking courses wouldn't count unless you were already employed by your employer, and maybe not even then, since you're not unionized.
The working mom you mentioned would only be given credit for her previous experience if it was with the same employer most likely, unless she was on a disability leave or some other formal long-term leave of absence.
There are definitely pitfalls to changing jobs. I'm afraid you're going to have to accept things as they are. They're paying you more than they believe they should according to their policies, so hopefully they won't decide to roll your pay back and claw back any overpayment they might think you've been getting. That would be even worse than just going with things the way they are. I'm very sorry this happened to you and I hope others how read your story will be very careful when they accept new jobs.
