My mind won't think of the word that i'm looking to use, what is it called when you go to work on the dates that you can, but need a really flexible schedule? so much

Maybe one of these? Lenient, adaptable, adjustable, convenient, accommodating, versatile, undemanding, lax, liberal, elastic, independent, agreeable, compatible (with one's lifestyle), self-reliant, unrestricted, self-sufficient, carefree, casual, unrestrained, informal?
