My sister worked in care homes for years and knows all to well about the thick skin needed, she ended up having a mental breakdown after having a deal with a similar situation. It's not ok at all and even in men who don't know what they're doing, it's still not ok to just expect women to grow a skin thick enough to cope with regular sexual assault and just get on with it.
It was during Covid and lockdowns when my sister started being assaulted, she works in a residential mental health place and the residents aren't always some frail old man she can easily fight off if needed, staffing was already an issue and because if the isolating rules and covid it became even worse, her manager told her to "just ignore him" and was also told that maybe it's not the job for her if she's gonna take it personally. She'd already spent two decades putting up with groping and sexual comments from some people, being called names, being hit and slapped sometimes, but the level of sexual violence one man used was totally different and she feared she, or one of her coworkers, or other vulnerable residents would be raped. Thats the level of sexual violence that was happening and she's since learnt it happens in many places.
She needed the job and can't "just ignore" a patient and not provide care, she can't just ignore a man trying to pin her against the wall, she can't ignore a man stronger than her ripping at her clothes and trying to corner her. It's way behind the decades of groping and slapping of her arse or other stuff she'd tolerated.
Every penny of the minimum wage my sister was one was desperately needed to fund basics, she couldn't afford to pay for private therapy and the nhs waits for talking therapy was so long she'd left the job by the time she got her first appointment. It's like nobody wants to address this aspect of the job and look at ways to support care workers (which may actually go a long way to retaining them too) instead a lot of people simply see jt as "maybe you aren't cut for this, find another job" or "they can't help it, you need to just crack on with it".
My sister has since been diagnosed with ptsd, I hardly recognised her for a long time, even when she wasn't at work she was constantly anxious, constantly worrying about female residents and co workers and feel like she should be there to protect the others. She found getting a job in another local care home very hard because her manager had told other managers that my sister was expecting to pick and choose who she cares for. The care industry lost an amazing woman who always went above and beyond for the people she cares for and their families.
I'm sorry you've been sexually assaulted at work and I'm also sorry you're not being supported. My advice would be to keep complaining but also get some mental health support such as therapy that specialises in dealing with sexual assault.
