Burger King employees had enough of poor working conditions and put up big sign: WE ALL QUIT.

Employees at a Burger King in Lincoln, Nebraska had enough of the miserable working conditions they had to put up with, so they quit. Nine of them at once. And to make their point, they also put up a sky-high sign for all to see: "WE ALL QUIT. SORRY FOR THE INCONVENIENCE."

The poor conditions included 50 to 60-hour work weeks, according to ABC8, and working in an understaffed kitchen without air-conditioning that at times reached over 90 degrees, causing one employee to go to the hospital after becoming dehydrated.

After the sign came down on Saturday, the fast-food restaurant remained open and understaffed, with new employees who have quit days after starting.
