6.1. The plan applies to employees, other than the employees referred to in the second paragraph, who hold employment in a research centre within the meaning of section 6.2 and whose remuneration is paid out of the centre’s budget, if both the employer and the employees so elect by means of a poll.
Employees who, on 31 December 2009, contribute to the plan for employment held in a research centre or who, on that date, would have contributed to the plan for such employment had they not been absent without pay, receiving salary insurance benefits or on maternity leave, those who, on the date of the poll of the employees, are included in one of the four bargaining units constituted under the Act respecting bargaining units in the social affairs sector (chapter U-0.1) and those to whom the plan, if it became applicable, would not apply by reason of the regulation made under paragraph 3 of section 4 may not make an election for the purposes of the first paragraph.
The employees may hold a poll only after a favourable vote by the employer. The other rules governing the holding of a poll by the employees and by the employer are prescribed by regulation.
