Congratulations Inez, you have a FANTASTIC outlook on what resident's rights should entail and you certainly have a positive and respectful approach.
Any female resident in care should be facilitated where possible to wear supportive garments if that is what they wish. Refusing to assist in this simple ritual would be very damaging to the resident's self-esteem and reprimanding the resident for expressing this wish is very disrespectful. It seems that the culture of care of the facility where you work seems to focus on labelling residents as 'manipulative' instead of addressing their
5 universal emotional needs. Unless there was a documented health reason for bra's not to be worn, we cannot see why this should be disallowed.
I can understand that it must be difficult for you working as a casual in this facility as you are probably limited to how much you can influence the culture or make any real change to the daily experiences of residents. Showing concern for a residents wellbeing is not "intruding, becoming too close or showing favouritism" it is having a
Spark of Life Approach that respects, empowers and lifts the person with dementia!
If it would not cause any further trouble for your darling resident, I would suggest continuing to assist her in whatever way you can. Try not to be too influenced by negative staff members and keep a positive, flexible approach where possible. As a casual, perhaps you can investigate other facilities where they have a more respectful and proactive approach.
