An Ernst & Young (EY) office in western India, which employed a 26-year-old who allegedly died after facing a high workload, has operated since 2007 without a state permit which regulates work hours, a senior government official told Reuters.

EY India Chairman Rajiv Memani expressed regret for not attending the 26-year-old employee's funeral, whose death is alleged to be the stress caused by work, reported the news agency PTI on Friday.

India is investigating the work environment at Big Four accounting firm EY, the labour minister said on Thursday, after the death of a 26-year-old associate worker was blamed on stress by her mother who demanded accountability.
