Flexibility in work could mean many different things. It could be that you have the flexibility to work from home at times, or the time of day you start and leave is flexible.

you cant flex a volleyball but you can use your flexibility playing volleyball...whenyou bump,set, or spike the ball you are using flexibility to bend you back or do anything of that sort to get the ball.....is that good enough?

Flexibility is the ability to move smoothly without interruption. Adaptability is the ability to adjust oneself to different conditions than what one is used to.
