My advice would be to check with HR dept, Union Rep or line manager before making any assumptions.
As stated in other replies, there are no statutory entitlement to compassionate or force majeur leave.
The latter is interpreted by each employer with more/less rigidity but has now come to be seen as emergency/unforseen leave where one's presence is necessary due to accident/injury/crisis involving immediate family member or someone one is responsible for the care of. I have discovered that it is not for childcare, not for planned surgery etc. Of course, we all have annual/vacation leave to draw from and most empoyers will be sympathetic where one has exhausted such leave.
