Sometimes we have difficult placements , but we can always refuse them , our punish is they make us wait , but i understand.
The plan care not always is completely trustful and sometimes instead of saying that we can do it , should ask first . To give an example it comes in my current plan care that we should sore "holes" in clothes , no one asked me if i was able to do it , and no I am not, so first is better to ask us and then write the plan care, because not all care assistant do such things.
