Glad to see this update.
I work in adult care and at my company, this is the default. Some men feel much more comfortable being supported by male staff, and it goes beyond personal care. Some find it more dignified to have men assisting them even with taking their medication. You can sometimes visibly see the rapport forming between elderly men and male carers, and the same for women.
We do not allow male staff to be alone with female service users, because it is a safeguarding issue for both the woman and the male staff. Companies that allow it are either run by people focused on profit beyond all else, or the clueless. Firstly, the care industry has a hard enough time screening out the neglectful, abusive and careless as it is. A company that allows men to lone work with elderly women is eventually going to attract sexual predators as applicants, who will seek the position explicitly because of those opportunities the company has created.
Secondly, we work with vulnerable adults who need care because of deteriorating physical health and deteriorating cognitive health. They can struggle to remember what happened yesterday, but remember traumatic experiences from decades previously. Unfortunately, it can often be bad memories that surface most. On a daily basis, I reassure people with dementia about events that happened 40 or 50 years ago, that they think only happened this morning.
Tragically, one in four women is subjected to sexual assault during her lifetime. No-one is born old, and every single elderly woman who needs assistance with daily living today has had an entire lifetime behind her. That lifetime may include sexual assault as a child or as an adult. She may never have told anyone, and have repressed it her whole life.
This background means she may experience personal care as sexual assault if performed by male staff, no matter how innocent the intentions of the male staff. If she is suffering from dementia, she may also get mixed up about past sexual assaults and accuse current men in her life of the acts she was subjected to in the past. These accusations will then have to be investigated, so this is a safeguarding issue for the male staff.
Responsible managers who know their job avoid these situations arising in the first place.
