Yes probably IABU, but it's a right pain.
My DS has ASD and attends a special school. The education he receives is great, the head and his deputies are marvellous and they work miracles.
What is a right old pain is the communication. They email system is a bit hit and miss plus they run everything very last minute. Which is fine if you don't work, but I am one of the lucky parents who does. I have raised this issue several times, given suggestions like a Google calender, but they don't seem interested.
My gripe is parent's evening. I know it will be on a Thursday PM (annoying as I work Thursdays with little flexibility). The school shuts an hour early so I end up paying for an extra hour of child care. Annoying enough and another niggle to organise at short notice. Fortunately they run until 7pm so I can finish a touch early, pray to the TFL gods for a smooth tube journey, hope that the traffic isn't horrendous at our end and make it for one of the later appointments. Go me!
I log on tonight to find they have changed the system and the latest appointment is 4.45! That's not evening FFS.
Would I be unreasonable to contact to the school tomorrow and ask to be seen on one of my days off instead? My and dh's annual leave is precious beyond belief as DS1 struggles in all day child care and has different holidays to DS2 who is NT. I get that teachers have lives and shouldn't have to stay late, but these meetings are important (more so than for NT DS2 who doesn't take the bus to school). DH works away, but can get back for 7pm, but not 4.45.
