If your head sometimes winds you up, spare a thought for staff at Dolores Elementary in Los Angeles.

They were so disillusioned with their “domineering and not collaborative” principal that they set up a camp to force her out.

Complete with a tent village, portable loos and a portable generator, the protest camp was staged so teachers were in prime position to barrack Anna Barraza last Thursday as she arrived for the first day back after the summer holidays.

“We’re hoping that, with us willing to give up our comfortable night’s sleep at home, that will send a message,” said Vanessa Robles, who teaches first grade.

While the protest was never likely to get out of hand, local police still cruised the area to make sure teachers were “well behaved”. So don’t go getting any ideas.
