Well, maybe. But a happy and adequately-vacationed workforce is surely going to be more productive, so the loss might be less than it seems (citation needed here, admittedly).
And I guess it might mean a few extra jobs, which surely can't be a bad thing.
By all measures I've seen, the U.S. workforce is dramatically more productive than the European workforce. I suspect the amount of time spent working is a significant factor in that.
Everything I've read indicates productivity improves when you have employees who take vacation. I really like the idea of shutting down for a few weeks per year (in addition to normal vacation time, whatever policy that is). Shutting down means nobody is looked down on for not being there.
Perhaps. It'd be tough to swallow the hit in productivity though.
