Well, they've truly cocked up this time!
Nowhere in the TA did it mention we'll be back paid 4 months.
Simply, as a sign on bonus, we'll get a lump sum as a ratio of our previous salary. Of course it was P funded AT. That's the law!!
This is no different to other lump sum payments. ie profit share (the last 2 years being about the same as my missing lump sum payment. Was refreshing to see AT call it "slight") and 13th month.
How it's calculated (eg 1 x 1 month for 13th month or .045 x 1 month x 4 for lump sum sign on bonus) really doesn't matter. This wasn't a backdated pay increase. They've made that very clear. IT WAS A LUMP SUM SIGN ON BONUS!!!
I personally see this as NR's final salute before he goes back to looking after gold fish.
It's a shame the DFO, starting a new page, is defending the indefensible.
