Age Discrimination/"Too Old For Retail"

My manager does not speak to me at all. I was not trained properly on the computer. I clean the bathroom and the shop every day I go in. My hours have been cut from 20 a week to 3. My manager has made comments of not having patience for old people. (I am 55.) I am made to stand by an open door regardless of weather conditions to greet customers for hours at a time. The young girls check their cell phones behind the register and gossip.

I'm anxious all the time. I can't sleep at night. Younger women have been hired and my hours are going to them. Once cleaning the bathroom there was a tampon on top of the garbage I found this offensive and when I told my co-worker I would not clean the bathroom if I continued to see that kind of thing she yelled at me she had her period she wrapped it well in paper towel and she was not apologizing.

Regardless this job is over. Hard to find something in February. Here's the thing, I read a lot of you say HR is a joke; maybe so but if the job is gone anyway why the hell should I walk away with my tail between my legs? I DID NOTHING WRONG. What? Show up on time? Work late hours? Dress well? I am going to call HR. I don't expect any real outcome except maybe if I stand up for myself I won't feel like such a victim! I have already gotten in contact with a lawyer who informed me to bring any action I need to document this first with HR. If anything I will give the manager a headache. I don't care.
