It is understood that , Pharma guys have to visit doctors all the time to pitch their product. They have to be presentable in front of the client, As they are representing the company. Please write the circular according to your need about being clean shaved on the field.
Just a circular is not enough. All senior people should be the role model and if they walk in with a properly shaved, neatly groomed, well-dressed, but need not be wearing expensive dresses, well manicured fingers, no food stains on shirt, all buttons intact, polished shoes.... naturally juniors will follow. When I was heading HR, I was the only guy to come to office with proper dress with tie intact. Once the GM called all the HODs and myself and told them, in my presence... Just see NKS, all of you are marketing heads for different products and none of you can meet the standards of a marketing organisation. That day onwards people changed their attire and appearance. Even Graduate Engineer trainees, who come to office without shaving, were asked to come to office only with a clean face. There are plenty of PPTs available on Grooming and Etiquette available in CiteHR and you can conduct a training for your employees in batches. For that, you should first come neatly dressed. If you have a problem, call me over... I will conduct the programme for your company. You can watch my photos, videos in Linkedin, Face Book and Youtube at the following links to see how I appear, consistently, in all my training programmes.
