The man and woman in the picture are evidently dressed as what is known as 'punks' - they are wearing leather, heavy boots, fish-net tights (in the case of the woman), and they have 'mohican' hairstyles (shaved at the sides, and with a pronounced upright section of hair on the crown of the head, perhaps to look like the coxcomb on a cockerel bird). I can't make out the picture too clearly, but the man and woman may by their code of dress possible also have piercings and tattoos.
1) How are they communicating non-verbally?
Some people would say that dressing as a punk, or being a follower of some other similarly striking fashion of dress is aggressive and rude, and disrespectful. That is the extreme. They are perhaps dressed a bit like warriors, with the durable leather clothing and sturdy boots, and demonstrate they can endure pain by having piercings and tattoos. They are wanting to make an upfront 'statement' about themselves as being tough and hard. One could say that there is nothing feminine or elegant about the look, which might suggest a reluctance to show care and attention to others. In terms of their body language they look quite disconnected, yet relaxed, not standing to attention and slouching a bit on what they are leaning on. It could be a look of indifference. However they are smiling slightly which may mean they are kind and approachable once getting to know them, though possibly looking into the distance and hence perhaps not being connected with the present moment. Perhaps they are dreamers. Combined with the way they are dressed this might suggest vanity and aloofness which might mean they aren't useful in a practical setting. Some might say that people with artistic leanings, interested in fashion, think they are above mundane everyday tasks such as caring for people day-to-day.
2) Summarise the message you think is being put across by the individuals by their appearance.
As they are dressed as punks, this may mean they are tough, quite cold/callous and vain about their appearance. The way they are dressed, in a rough inelegant way, and the way they are slouching and looking into the distance away from each other, may suggest disrespect for others and the present moment. On the positive side, however, they are smiling a bit and looking relaxed which might mean they do have a soft approachable side. An interest in artistic fashion, whilst perhaps indicating vanity, might also indicate an interest in the tactile and the power of art - which is to create interest and inspire through detail and daring. This may mean that they would care more deeply about the welfare of people in terms of their identity and their personal interests. It does not necessarily imply also that the individuals are impractical at day-to-day tasks. In fact, their skill in dressing the way they do and the endurance of the act of having piercings and tattoos suggests practical strengths and ability (and will) to deal with problems they face in life. It certainly takes effort to dress in a precise style as they are, but it really depends on where that effort comes from. Is it a sign of leadership and willingness to be brave and stand out, or is it a sign of vanity and mindless following of a fashion they don't understand?
3) Being dressed in such a way may scare people being cared for, especially if they don't understand why the individuals are dressed in that way. They may not know what a punk is and may think that they have designed the look themselves to look scary, or because they're mentally unstable. If they have pre-conceptions about people who dress like that, they make take offense and consider it disrespectful, or may have more old-fashioned views whereby they do just think it is disrespectful, whatever the reason is for dressing that way. In terms of their body language, the aloofness might be disconcerting, the slouching might cause offense. However, if the person being cared for is able to see the smiles they would be reassured by that and perhaps have a very different view simply based on the facial expression alone. For people who are very ill, facial expression and communication is a very important factor. If they are too ill to care about personal appearance of carers, it is the bearing of the carer and the kindness in their face that is the most important thing. Employers of the carers might take a different view, but this might be influenced by prejudice based purely on looking at the individual and not considering their skills and behaviour which can be entirely separate from the person's appearance. People dressed in this way do however often challenge that attitude of prejudice and that can make the prejudice worse as it becomes a battle of wills. But often people who dress this way have strong beliefs about the way people should be - strong and unafraid of what people say about you. Or they may just be vain. But interviewing them would help to discern this.
4) Though wearing a uniform strips a person of personality in terms of the way they dress, they should be able to keep their personality whatever they are wearing, as it is mainly in their face and bearing. A way of dress like this can be something to hide behind for people who are insecure about their bearing, face and personality. For older people certainly, uniforms are a traditional way of showing respect, and the idea is that once you are in your uniform it actually changes you into your work mode as you are under scrutiny and are highlighted as someone who is responsible for things. Badly cut uniforms made of nasty material are unlikely to be popular with workers, but if this is kept in mind, trading off against practical aspects of the clothing and hygiene, all concerned should be happy.
1/2 The individuals in the picture and communicating non-verbally through their clothing, facial expressions, and their body language/posture. The two individuals are dressed in "rocker"/"punk" clothing that is probably made of "tough material" like leather, dark colors, and contains metal/sharp/pointy edges. This clothing, along with their a-typical hairstyles gives an air of anarchy and non-conformation to the societal "norm." It could portray air of confidence in ones individuality and an abrasiveness towards other. The man has one leg up which is commonly an assertive posture. The women is glancing over her shoulder smirking. This body language seems to say that these individuals are not concerned with others due to their lack of eye contact.
3. This appearance could affect their ability to be a healthcare worker because people who are entrusting their well-being to someone else are looking for reassurance their their healthcare worker is knowledgeable, compassion, and honest. These qualities are often displayed with a clean and well-put together appearance and caring is usually showed with a smiley disposition.
4. Uniforms have long been a standard for blue and white collar workers and professionals in many fields. A uniform is a symbol of training or specialization and simultaneously sets someone apart from others while also showing belonging to a group with set standards. When a healthcare worker wears a uniform it immediately tells someone their position (i.e. nurse) which is different from any random person taking care of them. It also tells us that this nurse earned his/her uniform by adhering to a certain set of standards (i.e. he or she is wearing scrubs and IS a nurse because obviously this person has studied this profession and passed requirements).
