I don't think an increase in retirements will by itself lead to recalls. The company will simply cancel the LTRF and other staffing programs put in place over the last year and just like that!!.........staffing problem solved with no recalls. The 147 are contract pawns. They will not be used for staffing until the contract is making progress. It's just fantastic leverage and I don't see the company parting with it's favorite contract tool any time soon.
Plus people coming off of leaves starting this spring won't help either.
