I'll try and stick to the facts.
I started a new job six months ago. Full time. I tried to negotiate compressed hours (5 days into 4) but they wouldn't allow it. They allowed me to do 4.5 days but reduced my salary by £4k.
Six months down the line, it's becoming clear this role is too much for me to do on 33 hours. I've requested to go back up to 37.5 hours with the original (+£4k) salary.
They've been sitting on this for two weeks now and haven't said whether they've approved it or not. In the meantime, I'm working weekends and evenings to just stay on top of my workload with no extra pay.
Their reasoning is that they can't increase overheads, but they're also trying to double the size of the company in three years.
AIBU to ask for this? And AIBU to think they should have planned for a potential increase in salary based on their very ambitious plans?
