Has this scenario played out more than 30 times in the last 90 days?
If it has, have you considered filing to make it a "newly created" full time job and bid under Art 3 Sec 7 of your Supplement?
May also be a newly created classification that wasn't negotiated for in our CBA.
Also, watch to see if they aren't coding this time erroneously to "safety".
That's how they do it in my building.
Been waiting about 6 months to get these grievances heard here locally.
