The Chief Executive and co-founder Jack Dorsey of Twitter Inc surprises his employees by giving them a third of his stock in the company.

In his twit on Thursday Dorsey said the move, worth $200 million, is to "reinvest directly in our people," however Twitter was silent about the decision taken.

The unusual move comes as Dorsey works to rebuild employee morale and confidence at Twitter after a spate of high-level departures over the past several months.

He announced last week that the company would lay off 336 employees, about 8 percent of its workforce, in an attempt to streamline Twitter's products and teams. he added, “I’d rather have a smaller part of something big than a bigger part of something small,” he wrote in a tweet. “I’m confident we can make Twitter big!”

Dorsey, who took over as interim CEO in July after Dick Costolo resigned, also tweeted "I'd rather have a smaller part of something big than a bigger part of something small." His appointment raised concerns among investors about whether he could run both Twitter and mobile payments company Square Inc, which he co-founded.

Dorsey disclosed in Square's IPO filing earlier this month that he plans to donate 40 million shares, or 10 percent of the company, to a charity foundation he started that invests in artists, musicians and local businesses. He has already given back over 15 million shares to both Square and the charity foundation, he said.

Last week, former Microsoft Corp Chief Executive Steve Ballmer said he has taken a 4 percent stake in Twitter, making him the third-biggest individual shareholder in the social media company. Ballmer now owns more of Twitter than Dorsey, who has a 3.2 percent stake, according to Thomson Reuters data.

In his twit chief executive at Twitter said ,“I’d rather have a smaller part of something big than a bigger part of something small. We intend to make this big!” Now he has implemented another button on twitter that allows users to make purchases and a feature that shows users the best tweets and content on the site.
