Little perks can make a big difference , and they aren't always just perks . Letting employees take time off for doctor's appointments , or letting people come in a hour later and leave an hour later if that suits their lifestyle better . I think in today's business world , the idea is that you can treat people like dogs ( or worse than dogs - dogs have gourmet organic food these days ) . 
Question: What may be a good reason to give perks in today's business world ?
It's makes working more humane .
