this morning, when i came into work there were some picket lines on the entrance to the university (i work on a campus site). the protests are for teacher pay rises and tuition fee complaints.. anyways, i carried on riding (at a fastish pace), people got out the way (i guess it was clear i wasnt stopping) and some guy started yelling out that i was crossing a picket line, blah blah blah...
i was wondering what a picket line actually stands for? and what crossing one means? i thought they were just a way of making people notice you.. but crossing one seems to have some significance??
