Got to vent

Ok, so I just got home from work, and I got told I hid my seething anger well. No one, not even my bro, knew how frustrated, pissed, and loathed my store and position last night. Let me start at the beginning. I hurt my knee last Mon. night and left early. After much convincing of associates, I filled out an accident report. I went to the ER on Tues and was told not to work. I had a brace on my leg, and was to not work if it hurt to stand or walk. I brought the paperwork in to my Assistant Managers and a Co-Manager(Fran) that night. Fran asked what I had done and I told her I sprained the knee working the night before. Assistant Betty asked as well when she took the paperwork. I mentioned that I caught freight and hurt my knee and shoulder, but the shoulder was an old injury and I wasn't concerned by it. It was the knee that I had checked. They asked when I was allowed back, looked at the sheet and said there was no date on it. Fran told me that I couldn't come back to work until I got a date and was 100%. I said I would call the ER and ask them for a release note. Later that night I noticed on my copy that I could return on the 26th. Where the doctor said to me if it was better, I called in and used some sick time because it hurt to walk on it, even with the brace. Since I didn't feel 100%, I stayed out of work. Yesterday I get a call from Personnel(Cleo) and was told I needed to go to workmed. She set a time for that day and I went in. When I got out I called Cleo to let her know what the doctor said and that I could bring the note up then. She informed me she would not be in until 10pm and to meet her then. So I waited and went in around 945 to the office to find Cleo, Fran and another Assistant waiting. Cleo took my note, said she needed to talk to Fran and left. I had not punched in yet and was waiting to hear from Cleo what they wanted me to do for the night. The Assistant tells me I have to go with him and gets up. I followed into the personnel office and the door was shut and locked and Fran had me sit down. Then she proceeded to tell me that she didn't think that I injuried myself at work and "why did you tell me to my face that it happened outside of work and not to worry about it that you would be in the next night?" She also went on to say " I don't think the company should have to pay for this and I am going to see that we don't. I am going to interview everybody in the office that night. I bet if you think long and hard you will remember telling me that you didn't do this here, that it was and outside accident." She continued with " I am dissapointed in you, your a support manager. As such you are suppose to set and example for the associates. When you tell me something I would like to take it at face vaule, but then you change your story in a couple of nights and I don't know why." She also told me it was suspicious and fishy and she would get to the bottom of it.
Now I ask, how am I suppose to respond to all this? I am not even on the clock yet, went in willing to work even though I have to sit my entire 10hr shift, possible looking at sitting up front and saying "Welcome to Walmart." all night. What could I say? I did tell her I remember her telling me I couldn't come back unless I was 100%, but I can't remember ever saying I never hurt myself there. Hence the "if you think long and hard" speech. I really just want to say you fucking lying bitch, how dare you accuse me of being a liar when I have done nothing but work my ass off for this company dispite all the shit I go through on a nightly basis. That I continue to pick up the back room four nights a week, knowing it will look like shit when I come back in. Getting my associates to work at 110% everynight, even though it will never be good enough for her. To do all I possibly can, including half of my night Assistant Manager's job on many occassions, to get blamed for hurting myself and blaming them??????? Just my opinion. I did what a good support does, I bit my lip and worked my night according to what Fran said I could do and then my overnight Assistant Managers told me to do. I behaved, kept my composure, and suffered through the longest night I have ever worked at Wal-mart.
Just had to get that out and off my mind so hopefully I can sleep. Now I am wondering if I should get my persciption filled today or not though. Something I will have to take up with Kat later I guess.
