refineries

The easiest time to get hired at one of the seven oil refineries in the Los Angeles area is during what's called a turnaround. These breaks, when the refineries are shut down for routine maintenance, are incredibly labor-intensive. And refineries want to get them done as quickly as possible.

So companies need enough people to get the job done. But those workers must have specific skills.

In this line of work, as with other U.S. industries, there's a skills gap.

The weather is warming and vacation season approaching.

And, just as predictably, the price of gasoline is rising. It does that every spring as refineries switch to more expensive summer blends.

But this year, the seasonal price bump is getting an extra bounce. Gasoline is costing consumers about 5 percent more than last year at this time, even though oil supplies are abundant. Why?

Experts say U.S. retail prices are nudging higher in large part because Gulf Coast refineries are sending more gasoline to other countries.
