Self explanatory really..
If you signed it why? Why do you feel you and entitled to more time paid? Do you think being in lockdown is more of a right to more time of PAID than people who have babies who are delivered early or need NICU stays?
I am myself on maternity with a 19 week old and i still do not think its fair to say 'i need more time off paid because i wasnt able to go to a mother and baby group' theres plenty of time to go after.
I can sort of understand if you are due to go back and cant find child care but surely you can be furloughed or claim SSP/Benefits during this time like the rest of the country?
