Probably, the most ancient job that paid salary could be soilder. Ancient romans used to pay soldiers with bars of salt. (sal dire means to give salt = soldier) Also the salt bars could be exchanged with other commodities so it worked just like money (coins) due to its unavailability in the past.
Later we have a very established career option of salaried employees with a monthly pay period. I have took up such an employment with the first pay period falling on October 1993 and a payroll processed towards me for 250 months (July 2014 is 250th) in one company's system or the other. A majority of those monthly salaries are from TCS.
Ideally, by savouring on the TATA salt provided by salary from TCS, one should always be worth the salt.
More than half a million employees are working under the industrial empire formed under the TATA group under the great leadership of visionaries like JRD Tata the founder of TCS which alone employes 3 lakhs globally.
A quote from JRD Tata - “Strive for perfection and you will reach excellence”
Remembering a great visionary on his 110th birth anniversary.
