That’s odd. Most groups like that have one login, and from there they pick the organisation. However, the money still comes from the same shared pot. If there are two wholly separate pots, they must be separate employers. If they’re separate employers, then I’d say they can’t take the money out of a different pot, unless it was a genuine change of employer. If they haven’t changed employers, then surely they can’t just take money out of a pot of an organisation that isn’t the employer, unless it was a transfer of funds?
