'June Sickness' Overview and Causes

A survey conducted by Mynavi targeting 18,000 full-time employees revealed that one in five respondents had experienced 'June Sickness' in their current workplace. June Sickness refers to a state where individuals experience decreased motivation in work and personal life, along with fatigue, around June after adapting to new environments. One male respondent in his 50s stated, "After Golden Week, with no holidays, my job satisfaction and sense of accomplishment decreased." Unlike May Sickness, climate change is also believed to play a role.

Corporate Recognition and Age-Specific Trends

46% of companies participating in the survey reported feeling that "consultations regarding employees' mental health increase in June compared to other months," acknowledging the growing trend of June Sickness. This condition was most prevalent among individuals in their 20s, followed by those in their 30s, indicating a higher proportion in younger age groups. A woman in her 20s cited "the dissipation of tension from working hard since April and a discrepancy between initial expectations and job content," while a woman in her 30s mentioned "low bonuses, frequent overtime, and fatigue from guiding new hires" as causes.
