Hi EJ, you are paying for a service that is not being provided to you so of course you have every right to speak to the agency and insist on a new aide. After all there is no reason on God's green earth why you feel you should allow someone like that to take full advantage of your good nature. By requesting all of this time off she is not living up to her responsibility and she needs to be brought up short on that!! The aide has an obligation to work her hours as specified in her contract with the agency and if she feels she can't meet her obligation then she should clear out so someone who takes her job seriously can step in and give you the type of care and service that you deserve.
I agree with May that being an aide is hard work on a day in and day out basis but it is truly work that not everyone is cut out for.
Quite frankly, I think the aide who you had needs to know without a doubt why she no longer works for you. She did not do you any favors by leaving you in the lurch.
And most of all, please don't feel guilty about this!! This aide did not give you good service and it's not right that your health and happiness be affected by an aide who did not live up to her obligations to her client, which is you!
AS far as you're concerned, you are Number One which means you are fully entitled to the best help that is available.
