22.3 jobs have always been confusing... to most folks. The company has done everything to stay within the confine of the contract (kicking, scratching and clawing the whole time!)
22.3 jobs were a concession by the company, a concession they did not want to see, and the company will not give an inch to create additional cost by allowing OT.
It is cheaper to add a PT employee than to pay OT. If you were running a business you would do the same thing.
A couple of additional points....
Home Center - which operation will benefit from the OT and which operation will have to pay it? This has always been a big mess - pay was a major issue at the beginning of the 22.3 process along with training, job assignments and transfer rights, etc. etc. etc !!!
Initially, there were employees that were working longer than their alloted time on the 1st shift which caused the second shift to have staffing issues and get behind. Now the employee can no longer work past the schedule and must report on time to the second shift. Any scheduling changes must be communicated by the Home Center to the other shift.
How do you think that usually works? LOL!
OT is an expense that is easily controlled for inside jobs. If a manager can't control it, the division manager will find someone who will control it.
At the West Coast Air Hub - this is usually a major problem the last 3 weeks before peak. The union and labor agreed upon a course of action that seems to work well. There is an other work sign up sheet. With out going into to much detail there are some rules that must be followed. Any employee can sign up for extra work on one additional shift. If you fail to report 3 times (or they can't get a hold of you) you are off the list until the next month where you can sign up again. I used to have a shop steward help make the calls .... this eliminates the distrust.
Like I said, this seems to work very well....during this peak time frame there are no additional PT employees to work so 22.3 are allowed to participate if they sign up the previous month.
