You owe it to yourself to look after your own needs. Never should doing so for someone else come at the cost of your own. I am so very impressed you are not only giving yourself the freedom to take charge but to also stand up for yourself.

If you get flack one solution may be to divy up taskings and responsibilities. The way to approach this is two fold. Arm yourself with a list; actually say 'I am/so-and-so is prepared to do one or the other, you choose and I/they will do the other task. Work your way through this list - which ought to be succinct and short. I did this as a new leader in a cafe that was a total schmozzle. It worked very well at dragging all staff into an equitable division of responsibilities.
