"Shooting at ups-sf", having worked there in the late 80s, before computers for delivery drivers. I am not surprised. Bad Corporate Culture of overpaid, private stock only managers constantly Yelling at union but underpaid delivery drivers, "tossed loads" instead of "rough sort" by nightshift Loaders to be sorted properly off hub property!, too thin 3 tires on slippery set Winter rain roads!, before CC climate change, and rookie coarse shirts that cut the back of your neck!

News reported it was a UPS employee shooter.

So before Any anti-gun,  IGNORANT, loud-mouth spouts off,  this shooting was partly UPS's Fault. Don't  blame a gun.

Other than the annual mandatory Smith System driver training,  UPS created and for too long ran a Very Hostile work place environment for the lowest rank,  the front line,  the semi drivers and Especially local delivery drivers!

Oh,  and not all vans had a plastic semiclear, sunlight ventilated roof so you could see easily in the package back area. Had to open back door.  And fresh air ventilation to breath?
No a/c.
Vans were never washed inside,  either the dusty back or the dusty front; Just the outside 'image' was regularly washed.

So I left and happily, Much less stress,  drove a SF beer truck.
First driver to change into 'Indian Summer' shorts after leaving the China Basin Miller warehouse! Castro boys loved it,  and thus so did my redneck boss!
