Next Step in My Work/Livelihood

As my contract with Minaris Regenerative Medicine as Senior Executive Assistant ends on 3/15, I am wondering whether it is in my best interest and the I interest of all concerned to start another role – as early as 3/21) as
1) Chief of Staff to the CEO Levi Kelman (he seems to have issues) at the Blue Onyx Group Companies (if so should I start as a Conteactor and now out after 3 months or longer term as a full-time hire) or
2) Keep applying for Chief of Staff / Executive Assistant roles?
