I don't understand this. First they beat you up for not having a degree, then when you get one, you aren't supposed to tell anyone you have it. In the environments I worked in - I did a lot of medical videos, and everyone I dealt with had a million post nominals - all kinds of nurses and specialists, and every single qualification was listed after their names in their email signatures - and any grant writing we did required us to list our educational requirements - even a "B.A" after your name - per the guidelines for the grant. If someone handed me a business card with an MPS after their name, I wouldn't think they were being pretentious, I would simply think- "they have a Masters degree" - I've seen plenty of business cards with "MBA" after a person's name. Why should other graduate degrees be any different?
