Twitter Inc has decided to win their employees over by granting varying amounts of restricted stock depending on when the employees started working, in order to make up for the value they lost since joining the company, the Wall Street Journal reported, citing people familiar with the matter.

In a pressing move intended to reign in talent flight for another six months to a year, the company is offering compensation packages in addition to cash bonuses to some employees ranging from $50,000 to $200,000, the Journal reported on Wednesday.

“Competitive compensation, strong leadership, and a confidence in the direction of the company are all key elements to having top talent,” a Twitter spokeswoman said in an e-mail.

“We are investing in all three areas to ensure we maintain these employees.” she said, without giving further details.

Twitter has been struggling to keep talent at the company as stagnant growth and a dipping stock price have stirred concerns about the company’s future.

Four top executives left the company in January, the biggest leadership changes since co-founder Jack Dorsey returned as chief executive last year.

After returning to the company he founded, Dorsey said in October he is giving a third of his stock in the company, about 1 percent, to the employee equity pool.

Later that month, Dorsey spoke about “hiring and investing in talent” and the need for “bold rethinking.”
