The company I work for does this. The non-fanfare way it was described to me implies this is not rare across the industry.

Edit: I think the parent poster was talking about RSUs (pre-IPO) that cannot be sold to pay off the required tax. My friends at companies in this pre-IPO stage hold the RSUs in the employees' names until the IPO permits the employees to sell RSUs to pay the tax. The companies also let employees recieve the RSUs and pay the tax themselves if they want to, but nobody I know has done this.
