Totally fed up too Ollie.
Am a landscaper, had two bouts of flu (one swine) at start of 5 week job first thing in November. Been on back foot ever since, deadline was pre-xmas and had no chance. Client owes me +£12k which is contracted to be paid at job end (wont do that again - will do more, smaller stage payments). Not been able to work since week before Xmas week, got about ten days left on that site, lost another job in the meantime due to a tight deadline (totally unrealistic by client at this time of year, I wanted to decline it but he's an existing guy)and the boys all need to be paid plus all the suppliers.
So yes, not happy....
