Another burr in my hide

Several years ago I had the manager from hell (MFH). She insisted that I go on intermittent FMLA, and against my will I did. The only value of it to me was job protection. No one would be able to judge my job performance by my attendance. However, when review time came up the question of my punctuality (skewed because of early appointments) and attendence (skewed by FMLA covered health events) was graded. I objected, but was shot down not only by MFH but by the POS HR person assigned to our group. A few years later MFH insisted again that I go on FMLA. I patently refused. Why should I go through that effort if it wasn't going to benefit me?  A big stink was raised about it and it made it's way to HR. We had a new HR representative who looked at my evidence of abuse and shot MFH down. A few months after that she was strongly recommended to retire. I don't know if that situation had anything to do with it. Fast forward to last year when manager from Heaven and supervisor from Heaven asked me to  take intermittent FMLA. I explained and showed records attesting to the fact that in my opinion it wasn't worth the effort. They assured me that the situation wouldn't happen again. The are the MFHeaven and the SFH so I reluctantly took their word for it.

Screech into today. I had a performance review, the one that influences my pay increase for this year. Over all it was positive. But the one significant area of regression was in attendance and punctuality. I have had a lot of health issues come to the surface lately. According to FMLA, that question should not have even been allowed. That is the only benefit that I derived from taking intermittent FMLA in the first place. And I had been promised that this wouldn't happen again. It did. I objected. SFH at first tried to skirt around it but then consented to talking to HR about the situation. I don't want to step on her head. I truly love working with her. This is a really good job situation for me. I didn't call HR today. But thinking about it tonight, I can't see how this stance is in my best interest. I am walking it down to HR tomorrow. If this isn't addressed, in the least I will never pursue intermittent FMLA again. It's worthless.
