With attitude and unprofessional conduct like that it is easy to see why you are not being paid more richly.
1. If someone is not happy with their pay or thinks that their skills are worth more than they are being paid, then they should go and work for someone else who is willing to compensate them accordingly.
2. Don't give me the freedom of expression crap. When someone puts on a uniform and goes to work they represent The Airline, they are on The Airlines time and they need to fly the company flag, portray a positive image of the company, conduct theirself in a professional manner keeping any personal dissatisfaction out of the public view. On their day off they can do whatever (legally) they want.
3. Fuel prices are way up resulting in decrease profits (or even losses), and ticket prices keep going up while ameneties are being cut.... The last thing that I want to see or hear while I am paying more for less is some basically unskilled laborer whining and complaining about how underpaid they are... If you aren't happy, go see item number 1
