To what has already been posted I would add this: the overheads for a small law practice are relatively fixed. Insurance, Subscriptions, Rent, Heat and Light and Support Staff ( say two secretaries and a perhaps part time bookkeeper) will run to €80-100k in even a modest office. The solicitor who bills €150k per annum in this environment has a fairly modest income. The solicitor who increases his\her bills by 33% ( i.e to €200k) will practically double his\her income (as the overhead will not move much). So there is a big incentive to work long hours and perhaps to under-hire solicitor employees. This is just the nature of the thing (and I am not complaining about it) - but it is one of the reasons why so many solicitors work long hours and are generally stressed. But it is also the reason why even a small-ish downturn has a disproportionately large effect on the solicitor's income. Leverage has a way of biting you in a downturn and that includes staff leverage.
I second MF1's comment about billable time not being anything like the same as time spent at work - and you don't need a recession for this to be the case. About eight years ago ( in a small rural practice) I kept very diligent timesheets for a full year - even though most work was not billed by the hour. In a small mostly conveyancing practice ( I did not do any litigation at the time) the billable hours in a very busy year came to about 1,500 and the actual fees were circa 225,000 ( I can't actually remember if this was before or after Euro - I think it was Euro).
