Example: To hire his "employee"

Employee in English refers both to a male or a female employee. When in translation, is it OK to say just موظفه or should we include an additional pronoun ending to refer to both the male and female; i.e., موظفه/ته? Should we follow this throughout the document with all the possible terms that require the additional inclusive pronoun?

Is there a convention one must follow?

If anyone can shed some light on this I would highly appreciate it.
