I can confirm you, this is only the SIDL Crew that were stuck outside because of border closures, on the other hand, Crew that left on ULV in May are all laid off outstation or in the process of receiving emails and phone calls...
This said, SIDL crew that Is being called back are made to sign New Contract with a Basic of 2800QAR depending on how many years they have been in QR & mostly who were stuck outside are Either CSD, CS, and or F1s..
On the other hand QR is operating with a Min Crew, like on a recent flight to a European Country there were 200 Y Class Pax and only 3 Cabin Crew- it was Hell for those poor souls” literally working like slaves at FL340.
