It's fine for boss names ending in s to be displayed as s's. For singular nouns that aren't proper nouns, you always make the possessive by adding 's even when the noun ends with s. For proper nouns ending in s, possessives can be formed by either adding 's or just ' so for the sake of consistency and simple code, we can add 's in all cases.
