Long hours mean facetime - the illusion of working as hard or harder than your peers. I've worked in industries where this is the norm - it's terrible.
Especially if you actually are more productive than others, because then you're in a situation where you know you're working more hours than you need to, being unproductive, yet you know that the more work you finish, the more will be put onto your plate and the less likely you'll ever be able to have a decent work-life balance. So you wind up sandbagging it, put in the facetime for the hell of it, and look for a new job...
