I think either a uniform minus the tie..... or NICE business casual.... nice slacks with a COMPANY polo shirt would be awesome... never gonna happen because too many of the guys think the uniform shows respect.... personally I think it looks like a bus driver. In the last 30 years the world is full of companies who relaxed their dress codes to find in almost EVERY case... the employees become much more productive and enjoyed their job. Now I am not talking about a total relaxation of the dress requirements mind you just a tweaking... as has been mentioned ....HAT... ugh... tie.. UGH.... Again I will say it... nice black shoes... nice pressed slacks... uniform shirt with epaulets ( or a nice polo ) ... and wala.... you just might be surprised at how the employees react and how much MOST passengers would support it>
