A Golden hello is a bonus offered by hiring firms if the hired joins the company from a rival firm. It is very similar to the traditional joining bonus offered by firms but will be offered usually for rival firm employees luring them into a firm.
Typically, "Golden hellos" are offered only to high-ranking executives by major corporations and may entail a value measured in millions of dollars.
In the UK a 'golden hello' is a financial incentive to teachers training in shortage subjects for secondary education. The value varies according to the subject with Science and Maths attracting £5000 where as music is offered £2500. The incentive is paid by the TDA teacher development agency.
