On 18 April 2014, in one of the worst disasters to ever hit the Everest climbing community up to that time, 16 Sherpas died in Nepal due to the avalanche that swept them off Mount Everest. In response to the tragedy, numerous Sherpa climbing guides walked off the job and most climbing companies pulled out in respect for the Sherpa people mourning the loss. Some still wanted to climb but there was too much controversy to continue that year. One of the issues that triggered the work action by Sherpas was unreasonable client demands during climbs.
