Little perks can make a big difference , and they are n'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 ) .
