If you have access to MODNET read the JSP. It’s a couple of years since I looked at it but I believe you can be paid For your new employment while on terminal leave. For other leave you can apply to have a second job, which allows you to be paid for that too. For resettlement you are not allowed to be paid. If the company insist on paying you (Union rules etc) then you are supposed to declare it and pass it on to the MOD! Your P staff should be able to help (I say should because mine were useless) watch out for gotchas with HTD if you go for the Civilian Workplace Attachment option!
