I know I've already replied with some useful threads but thought I'd add that my company were initially really good about me taking time off as I was completely honest and upfront.....they allowed me to have time off for 1st IVF and both FETs....although I did get signed off by my consultant from either EC or ET.
However after that they got really funny with me and told me in no uncertain terms that it was "elective" surgery and it would either be holiday or unpaid leave. My boss even asked "how many times are you going to be doing this ?!" (errrr, basically as long as it takes mate !!!

) I also got told that if I took any sick leave for it I would be slapped with a disaplinary....and when I said about being signed off by consultant, they (HR) told me if they found out it was for IVF then I could also face disaplinary !!
I decided that since this was their attitude then I wouldn't tell them when I would be having treatment....I mean, I don't tell them when we have "baby making sex" so why should I tell them when I'm having "baby making treatment"

!
I then had to have an op for my endo etc in the February (last year) and obviously got signed off for 2 weeks (my work are fully aware of my endo as I've had several ops for it, they knew before they employed me and they can't do anything against me because of it !).....but HR called me up when I'd booked the time off on the holiday/time off system to ask me if this was "essential" surgery or was I choosing to have it done ie "elective".....I told them truthfully that it was for my endo so not much they could do about it !
I had another IVF in March/Apr 07 and again in Sept/Oct 07....neither times did I tell my work. On the last time, I got a BFN and still came into work that day but was due to go to lunch with some colleagues to celebrate completion of project (and also one of the guys last day at work).....got very p!ste and didn't return to work (which was actually expected anyway as none of us did !!)....I phoned in sick the next day cos so upset from BFN (puffy eyes from crying), heavy bleeding & cramping, migraine (always get before AF) and yes, admittedly, a bit of a hangover too if I'm honest so a bit naughty I spose....anyway, boss went a bit mad when I came back into work next day and I just said fine, I'll book it as holiday but just for information, we had our 5th unsuccessful IVF (3rd fresh but 2 FETs - didn't explain about chem pgs with FET as he'd have no clue !) so yes, whilst I admit I didn't come back after a LATE lunch (we didn't go out until 3pm !) and that I wasn't the only one...and I phoned in sick....I did actually have a good reason as was getting terrible cramps and heavy bleeding, migraine and also did not feel like facing people and putting up with
[email protected] at work !! He did actually apologise but I still had to take it as day and half holiday (half day even though from 3pm and then one day for the "sick" day as apparently I wasn't really "sick" )
This time round no-one knows (well couple of colleagues who look out for me) but not HR and not my boss....all time off has been holiday and I came back to work the day after ET.
I've been at this company for over 10 years now and sometimes I feel like they really don't give a monkies about their staff....and they seriously need to look more closely at their IVF policies.
Anyway, rant over

but just wanted to let you know you're not alone !!!
Good luck & take care
