Exxon's upstream and downstream are both much bigger than Shell's. So you'd expect their work force to be bigger too, right? Per capita they just produce a lot more bbl or BOE per person.
Also Exxonmobil has historically reduced staff count by 3-4% annually. When Exxon and Mobil merged the head count was ~150,000. Now, 24 years later it is 61,000. That means more than 3% attrition (plus firing) per year. They have been annually hiring about 4% of their workforce... that means you guessed it every year 7% leave due to quitting, retirement, and firing. That is basically as big as the layoff that Shell does every 3 years. They just don't make a show of it and don't have the severance packages or voluntary nature. But every year, just before Thanksgiving, they fire people so they don't have to pay them for the holidays and they don't vest another year of service. Once ratings and rankings are done, they fire folks.
ExxonMobil has more turnover, but they claim they filter out more of the best and discard the bottom fraction. Just think we could treat people like replaceable cogs too!
The philosophical issue is what is the point of the corporation? Is the corp a social construct to enrich and benefit the shareholders only? Is there also a responsibility to the employees and their benefit? Is there a responsibility to society, morals and posterity?
I think it is responsible to all of these, shortsighted thinking is to just the quarterly numbers that are owed to the shareholders, that's what is wrong with a lot of corporations today. They really do owe something to the workers, society, and posterity too for the social construct to continue. It cannot be all quarterly gains otherwise you get the short term gains and long term bad moves made by CEO's lately.
