Pulling a sickie, taking a mental health day or just finagling a day away from your desk has become quite an art form for some ingenious employees.

Притвориться больным, ??? или просто обманом? получить выходной стало прямо- таки настоящим искусством?? для некоторых особо изобретательных сотрудников.

Помогите, пожалуйста! Особенно меня волнует taking a mental health day, да и другое тоже "хромает". Буду очень благодарна.

а вообще странно, что профессиональный переводчик не в состоянии такое понять.

If you feel the need to lie about it, just don't. Just say you need a day or took a day for personal reasons. (Even if it's for an interview or a mental health day).”

То есть mental health day не равен day off for personal reasons

На другом форуме мне ответили:
In the U.S., it's a slightly humorous expression that stands for taking a day off because you think you need to get away from work stress for a bit.
You never request a "mental health day" because there's no such thing officially and because mental health is a touchy subject in corporate culture. Usually, you ask for "a day off to attend to some personal business."

Непонятно...
