Terrible treatment of transgender employees

I am beyond fed up with this company's blatant malicious hostility for their transgender employees.

For context, I am transgender, as are several of my coworkers. All of us have to deal with our legal names being on the schedule, revealing our legal names to our coworkers. As if that wasn't bad enough, our legal names also appear on every receipt of every customer we cash out. I have had customers call me by my legal name because they read it off the receipt. Staples essentially hands out its employee's deadnames to every single customer, including the transphobic ones who harass us. (Management couldn't care less when it comes to innapropriate comments we have to deal with from customers)

HRConnect has a feature where you can tell Staples your "preferred" name (very insulting language for trans people), but it doesn't affect anything besides HRConnect. Schedules and receipts remain unaffected. Yes, I have asked my manager to change the names on the schedule; he prints the schedules as-is, then scribbles out the legal names.

One of my transgender coworkers was particularly incensed about having her legal name given to customers who regularly harass her. Being particularly motivated, she decided to contact corporate. The response was absolutely appalling. She was completely dismissed, told that the legal name was the only one they could use on the POS systems. Now, it's important to note that she used to work at Sally Beauty, and they use the exact same POS systems that Staples does. When she brought up the name-change issue to her manager at Sally's, the manager updated her name THAT SAME DAY. Afterwards, every receipt showed her correct name. We KNOW it is possible.

However, Staples Corporate insisted it couldn't be done, which she knows for a fact to be false. She called HR out on it, but they outright refused. She asked for a supervisor, then another supervisor. This turned into a WEEKS LONG battle with HR. They never relented. I saw her reduced to tears multiple times.

The Staples corporation has absolutely no care or compassion for their transgender employees. In fact, they actively antagonize them, and aid and abet harassment and discrimination at the hands of their customer base. But hey, they sell a Staples Pride shirt in the merch store, so it's all good, right?
