This year 2012, I will not try to be flexible as in the past years. I will not tolerate casual dressing by my vets or the staff or intern.
Sandals, T-shirts and jeans are out. Those who persists will likely get the sack as they cannot do what they like anymore. The young may think they are cool but it is just common sense. How can clients trust you when you dress as in sports shoes, sandals with your toes exposed and T-shirts with advertisements.
Dressing casually is out in 2012 and those who insists on dressing casually will need to look for another job.
