Unfortunately the people in ramp handling positions are often treated by others in the industry as the lowest of the low in the pecking order. Until such time as the so called professional members of the industry start treating the ramp handlers with some respect, and as part of the "team", they will generally continue to act in an "irresponsible" manner. People will normally work to the expectation of their "superiors". If you consider that they are careless and irresponsible, they will be.
I have the good fortune to work in an environment where all staff are respected as essential members of a team providing a product to the travelling public. Our "ramp rash" problems have all but disappeared, and new ramp handlers are schooled not only by formal training, but by peer pressure.
Take the time to pass on a word of appreciation to the folks out in the weather getting your aircraft ready for despatch. You may be suprised at the results.
