I've always been under the impresion that Air Contractors' EI-JVL was wet leased from Safair -- meaning South African crews and maintenance. I don't think any local crews were laid off -- just replacing Safair crews with Safair crews.
It is my understanding that Safair is owned by ASL Aviation Group based in Dublin, Ireland. They also own Air Contractors.
Air Contractors' EI-JVL went to Marshalls of Cambridge in early January this year for maintenance and then left for Johannesburg as ZS-JVL. ZS-RSG arrived in Shannon on 31 December 2013 and has been parked there since then. According to an Irish friend of mine, there are no signs of it becoming EI-RSG.
