First time poster so please be kind 
I work in special needs education. Absolutely love the job. Been in current job 3 years. Hours and holiday pattern suit family life, although I am struggling with my employer being incredibly inflexible when it comes to needing time off for dependants during term time.
I had a period of long term sickness last year for a bout of anxiety and depression, some of which was signed off. I returned to work and was put on stage 1 absence review, fair shout, I'd been off a lot. I was close to completing the process and being taken off review in April but came down with a nasty case of Bronchitis. The resulting time off took me over the level agreed in the absence review meeting, hence the whole process repeats and I'm back on review. As part of the review process I was asked to review childcare options as some of my other time off had been for care of DD when unable to attend nursery due to illness. In one meeting I was told that if DD was unable to attend nursery then I should be finding a childminder to take her if nobody could help out. Tried explaining the numerous issues with phoning a random childminder at 7am to look after a sick child but employer didn't seem to understand this. Was able to change childcare arrangements so that DM has DD 2 days a week on days when other family members might also be able to help out if DM unable to due to hospital appointments etc. I've made a real effort this year to keep absences to an absolute minimum. Time off for DD has been zero. She had chickenpox and spent the entire week with DM and DP has taken time off to wait for DM to collect when DD has been unable to go to nursery. I've had 7 days of absence over 3 occasions for sickness. This is low considering the amount of time others in the class and school have taken. The target set at my last meeting nearly 3 months ago was no more than 1 period of absence lasting no more than 3 days. I had 1 day off for a migraine, no other time off in that 3 month period so have met the target for time off.
On the whole, this year has been amazing. No issues with anxiety or depression, have had some amazing opportunities and feel I have really come into my own in the job and shown what I can do. My end of year review was glowing. However I feel I am still being penalised for my mental health issues last year as my absences this year haven't amounted to enough to trigger the review process, they're still taking last year into account, and for being a parent. I have requested some time off in July to take DD to sessions at her new school ready for September. There are 2 1 hour sessions on Wednesday mornings and 1 longer session on a Friday afternoon which would require leaving at 1:45. I feel these are really important for us to attend and I'd hoped as a school they would understand. I followed the procedure for requesting the time. It has been cleared by my class teacher. The sessions are luckily on good days for me to be out of school staffing wise. I handed the forms in before half term, so over 3 weeks ago. I was approached by the Head today as I was getting a child from the bus, so this conversation was had in front of other staff, students and bus drivers/escorts. I was told that I needed to find someone else to do at least some of the sessions or I would be escalated to stage 2 absence review, which includes a formal warning. These absences will be in the next absence review period so won't take me over my target for this current review period. AIBU to think that they could take these into account when setting targets for the next review period? It's not often your child starts school and these aren't going to be ongoing absences. I have given plenty of notice, no cover is required and the time off will be unpaid. I am a union member so am considering getting representation for any further meetings.
As a staff body we have repeatedly asked for a bank of time that we can book off unpaid for situations such as these, as we're unable to take any annual leave as such. We've also suggested some form of flexible working whereby we would be able to stay late or come in and make up time for absences for appointments etc but this has been repeatedly refused. I would really appreciate any advice here. Apologies for the long post.
