This character is an office lady.

An office lady is a female office worker in Japan who performs generally pink collar tasks such as serving tea and secretarial or clerical work. OLs are often unmarried and live with their parents well into early adulthood. Office ladies are usually full-time permanent staff, although the jobs they do usually have little opportunity for promotion, and there is usually the tacit expectation that they leave their jobs once they get married.

Often nicknamed shokuba no hana or "office flower", these women suffer discrimination due to the M-Curve. Office ladies are usually hired right after high school or junior high, with university graduates discouraged from pursuing this type of career. They are kept around the office for the youth they bring to it, hence the "flower" nickname. They are charged with routine, menial tasks meant to support the male workers. This type of career offers very little chance of advancement and was specifically designed so that women would leave for marriage before their thirties. Women between the ages of twenty four and twenty eight often are advised to settle down as a subtle message to quit, as those years are considered the most suitable for marriage.
