An online survey of 300 employers conducted by Mynavi showed 20 percent barred their part-time workers from sitting when attending to customers, while 24.3 percent said they did not set a clear rule but workers still stood. Only 23.3 percent allowed their workers to sit. A survey of 300 part-time workers, meanwhile, showed that standing negatively affects the quality of work, impacting concentration and motivation. As for why employers did not allow workers to sit, 33.8 percent said it was to prevent giving customers a bad impression, while 25.6 percent answered "just because" without stating a reason. The requirement to stand during shifts also affected hiring, according to the poll, with 19.7 percent of employers saying they had seen part-time workers quit due to physical factors stemming from standing during work. Over half of part-time workers also said they would be more motivated to work if they were allowed to sit. Nearly 80 percent of the employers and part-time workers said they would not mind being served by seated shop attendants.
