I went for six years without a car. The bus-service while craptastic was a boon in bad weather, better than walking.
For some reason though around 2005 everyone went batshit spastic about hiring people without cars. I found it very hard to maintain employment as a machine operator/programmer/setup monkey. The excuse was "what if we need you to run an errand" and the other excuse was "we wouldn't want to be responsible if a coworker ran you over in the parking lot by accident." I heard both of those excuses quite a few times.
Normally when companies do something like that you can find some kind of media event or trigger for their behavior, in this situation it just blindsided me... came out of nowhere.
For the first excuse, if I'm running a machine or setting one up you are not going to ask me to drop my tools and run to the store for another roll of TP. That's what you ask the idle operator who is waiting on my services to do. The second one, you wouldn't be any more responsible for a bike rider than a normal pedestrian so why the excuse?
References at the two companies that employed me for most of my biking-times clearly show I came to work rain or shine, snow or wind, every day... on time/early for my shift and I worked overtime as requested even if I had to bike home at night
*shrug* Their loss. Frankly someone who bikes to work is healthier and more fit than the slob who drives an SUV a quarter-mile to the plant gate. But hey, that person has an SUV not a bike so clearly he/she is the superior worker.
...well that nonsense is behind me I'm driving again and I won't willingly give it up without a fight this time. There is too much in the way of ageism out there I don't need the added "excuse" of biking to work on top of that.
