I've had to turn it off.
People moaning that they've had £1.3 million taken out of their profits and now they might have to lose two of their 30 units cos they are unprofitable.
Those are your choices mate. You don't "have to" do anything. Use the profitable units to support the unprofitable ones if you're that bothered.
Lowering the threshold costs £600 / employee. For a full time employee on minimum wage, say £22k a year, then the increase is a difference of £750, which is an increase of about 3% (assuming they have no other benefits and they will cos you need to pay them a pension for a start). That percentage will drop the more you pay your staff. Nobody likes being taxed but all this "I'll need to decide how many of my team to keep" reminds me of "tax me and I'll leave the country" that they always come out with.
