How it works:-
"Each full-time employee gets given at least £1,000 worth of shares every year. They can't cash them in immediately - they have to hold them for a period of between one and three years."
"HMRC rules allow employees to receive £3,600 worth of shares from their employer tax free every year. Most of these awards are below that threshold. The employee wins through a tax-free windfall, Amazon wins because it hasn't got to pay any cash out, which leaves HMRC as the big loser."
"the practice of giving staff shares is widespread, generally seen as a good way to promote loyalty and engagement - and is 100% legal."
