'Everyone hates me until they need me': 25 Under-appreciated jobs we couldn't survive without

You're due for a dentist appointment. 

How do I know? Because we are all due for a checkup–we're just procrastinating and pushing the appointment because everyone detests going to the dentist. That is… until we have a raging toothache and can't sleep at night. The dentist will always be the bad guy until we desperately need him, and for many jobs out there, that's a daily reality. Everyone harshes on lawyers, making fun of their firm-issued BMW–at least, until we find ourselves in a pickle, seeking legal counsel and an ally in court. 

So if you've ever felt under-appreciated at work, you might also be a quintessential employee in the cogs of the machine of society, making the wheels go round with every 9-5 shift, watching everyone be a hater until they beg you for your services. Scroll to read about some other jobs that we couldn't survive without; it may make you think twice about calling your dentist to schedule your annual visit.
