1. General Electric is famous for firing the lowest-performing 10 percent of managers each year. With its strict no-layoffs policy, Valero Energy believes people need to feel secure in their jobs to perform their best. Yet both are high-performing companies. How do you account for the success of such opposite philosophies?

Firstly i will discuss General electric philosophy. So, what happens is sometimes when you don't put pressure on managers then they become lethargic and slow. For this matter they needs reminder to stay on tip of their game. But at the same time its demotivating too.

Secondly, in Valero energy they believe in psychological safety, to make their employees feel secure and safe. It has great impact on employee performance.

Actually, company's performance is not measured by profit and loss alone. It also measures by other factors like employee safety, employee motivation, impact of policies on employees and bringing positive addition to the life of employee.

General electric is high performing company in terms of profit and revenue. They follow negative reinforcement philosophy.

Both concepts eargs the employees to perform better. But one approach is better i. e to make them feel secure and make them believe that company cares for their career, future and well being. That actually motivates the employee. In return employees works wonders for that company.

In latest HR practices, many professionals are shifting from General electric philosophy to Valero energy philosophy. Because it increases productivity of employee by positive reinforcement. Which actually is better.
