Three Catagories of work, service according to our shashtra

All kinds of work divided in three categories according to shashtra -

1) uttam: 

giving knowledge, education with character building, which benefit society is the top category  

2) Madhyam: 

Feeding people I.e. Farmers and kshatriya who provide security are exalted as second great service, work

3) Neech 

Working for own sake, selfishness I.e. all jobs , naukari (shudra) are categorized as lowest category, neech karma. What we see in today's world most of us aspire to become professional, however, few of us realize there is no professional ethics followed when it comes to making profit, money. Ultimately, we end up working for not a company, or for the sake of profession, but for serving our bosses, this is the form of slavery which evetually degrades us to the lowest level - अधम।
