Bill Ackman's secret to retaining talent: stock and Hamptons summers

Bill Ackman runs a big money company called Pershing Square.

The company takes care of about 48 people who work there.

Everyone who works at Pershing Square owns lots of the company's stock, worth many millions of dollars — even the cleaners and front desk workers.

Ackman believes in looking after his people so they do not want to work anywhere else.

Workers come to the office five days a week for ten months of the year.

In July and August, the whole investment team moves to the Hamptons, a beach area, and works from homes.

The company also provides healthy food, a gym, and good health benefits.

Ackman says no worker has ever left in a way the company did not want.

He started Pershing Square in 2004 after an earlier company, Gotham Partners, shut down.

He thinks artificial intelligence could be the next big advantage for businesses.
