The correct phrase is "all staff," not "all staffs."
"Staff" is a collective noun that refers to a group of people working for an organization or a company. As a collective noun, it does not have a plural form. Therefore, it is incorrect to use "staffs" in this context.
When referring to all the individuals who work for an organization or a company, the correct phrase is "all staff." For example, "The meeting is mandatory for all staff."
