Name changed as this is identifying.
I work full time hours on a sort of term time only-ish basis. My contract says I work 40 hours per week 42 weeks per year with 5 weeks of holiday/bank holiday entitlement - so 10 weeks of unpaid time off and 5 weeks of paid time off. The expectation is that I work during the majority of term time and take 10 weeks off per year during the Christmas/Easter/Summer holidays. I then can use the 5 weeks of holiday/bank holiday entitlement to take half terms and any additional time I need off. My year period runs March 31st-March 31st. I'm paid the same amount monthly.
This works great for me and I'm thrilled I'm allowed to do it. However I go on maternity leave in August (planning to return in May 2018) and I've been told by friends that it may be unfair that I am going to loose some of my 10 weeks off. I plan on finishing work in June and using the 5 weeks of holiday/bank holiday entitlement to take me through to the end of the Summer term when I will be off anyway. Maternity leave will be triggered when the baby is born in August. I stand to loose around 5 weeks of time off as a result for 2017 and it's not clear if I will loose any time in 2018 or if I will have the full 10 weeks entitlement.
Does anyone know my what my rights are before I go to HR? I don't want to push it too much as I am very fortunate to be in this position but at the same time if I could end up loosing 7 weeks of time off due to maternity.
Thank you so much!
