If a 25-ton push tug runs over my toes, whether or not the boots were steeled will make as much difference as would them having been painted orange. Even so, at one pound less than the weight it would take to curl the steel, how would unprotected feet fare? For those things I often handle that are less than 100 lbs. and may fall a few feet to my toes (bags, cargo, mail), I wear steel toes. Not to mention scrapes, stubs, and bumps that would ordinarily vex my little piggies. But that's just me; they're not mandatory (anymore) so if people have their reasons for not wearing them then they have their reasons.
I just wonder about the kneepads. I thought the contract said we were to be supplied kneepads? <_<
Regarding the supposed inevitability of injury during solo bin loading/unloading: I think there's no denying the risk inherent in it though I submit that as long as a person knows his or her abilities and limits, and is smart about how they're doing it, there's no certainty that he or she will become injured. I think about a guy I worked a flight with tonight: he's in his late 60's, skinny as a rail, curses like a sailor, smokes like a chimney, prefers to load and unload by himself unless it's a bigger plane and stacked deep (like most of us). He can do this because he knows what his body can do and doesn't push it and because he paces himself. And he's not the only older guy like this; there are dudes that will curse you out for trying to get in their bin if you think they need help and don't ask them. There are dudes that you know not to ever ask if they need help.
Also worth mentioning are a few of the string beans out there that look as though they have no place on the ramp yet stack 150 in the aft bin alone and standing up and make it look easy.
Now am I a "management suck-up" for having this kind of attitude? I don't think so; I'm regularly offered help when I'm in the bin and I usually refuse it, not because I think it will please my supervisor but because I prefer to do it on my own. Thinking about it, most of our sup's would prefer there be two of us in the bin for heavy ups and downs, but they let us make that choice on our own. As for sucking up to management, few here do it because, honestly, there's nothing one can really get out it; you'll still have to do the same amount of work as before and if you screw up you're still in as much trouble. I know what I'm doing and I'm serious about getting the flights out right and on time; that's worked for me better than has any kind of upsucking not just here but in every job I've ever had.
This said, one thing I won't do in the bin alone is stack/unstack and scan the bags. That I'd consider far less safe and it pisses me off because it messes up my rhythm. Anybody not at the top or bottom of the belt handling bags that wants to scan can scan all they want...
