At this point in the day, I suppose you might be getting a lot of responses from people who aren't working.
Or are working but just not at work? Shift workers, night workers, people who work weekends and have days off through the week. I'm one of the above and comments like that really annoy me tbh. I was awake, on the ball and working for 12 hours during the night, when most are sleeping and I'm awake now because life goes on around me and sometimes that wakes me up.
I wouldn't judge you OP, being totally honest, I probably cost more in claiming for childcare to work ft than had I been at home on benefits. As my DC is older, it's starting to swing the other way and I'm paying in slightly more than I get back, that'll increase as she gets older.
And the problem with being a single parent and working while child is at school is that as most people will tell you, especially here, you shouldn't consider school as childcare, yet expect you to when it comes to working.
You need to get into a mindset of not caring, which is a damned sight harder than it appears, because regardless of what is actually happening, you'll be judged anyway.
Personally I wouldn't judge you, you need to do what you need to do to survive and have a future.
