i don't think tc was going to sue regarding the accident. i think she was going to sue for upaid hours worked.
tc, i agree with the advice above to speak to HR and explain you need to scale back your hours because you are exhausted. you could reference the accident as why you have come to this decision.
when i worked for a large corporation and was salaried, they wouldn't pay overtime, but sometimes they would give us comp days to make up for hours worked. i think that would be reasonable to request.
and i agree also, perhaps time to look for a new job that appreciates you. that would also ease up the pressure on you with xABF.
i think that there is a lesson in all of this for you, as a codie, we tend to let people take advantage of us and we give, give, give. this would apply to the workplace also.
why not float a CV around and see if there is something else offered to you? you have choices here!
