I didn&#x27;t say they weren&#x27;t important. But, what a waste, when the doctor saves the life via an operation, the nurse administers care, and the patient dies from an infection  acquired due to a dirty ward, when it could be so easily avoided, by respecting the important role of the cleaner, starting with actually making them employees, paying them well, proper training, materials and care, and finally, giving them respect, so they feel proud, as they save the life just as much as the doctor or the nurse.
