f.i. or f.o.

f.i. or f.o (fit in or fuck off)is an informal reference to a controversial human resources philosophy whereby the employee is expected to conform to the prevailing organizational norms or get fired. It is also used to impose conformity to perceived racial, national, gender or societal norms. it is a "no-holds barred", "frank" and open assessment by a supervisor, who maps the employee's chances and alternate career paths boldly, forthrightly and unhesitatingly. This is said to be "not necessarily" to the employee's advantage. The acronym "f.i. or f.o.”, the neologism, the phrase and meme "fit in or fuck off", and the concept have been expanded and exported to other contexts. For example it is used as a justification for racism, nationalism (e.g., jingoism), ethnic, nativist, [immigrant restriction[ and xenophobic reaction, regulation and action. This idiom is a suggested direction that means to assimilate and be productive.

“Some fast food management teams describe f.i. or f.o., as the culture of a competitive meritocracy.”
