At our store we have to do our own and we don't get any extra hours for them. We get them done however we can. Here are some things we do.
1. Set several endcaps at night so the opener can push them. (depends on your store, 1 week we can do this and the next the STL will spaz out)
2. Have an endcap 'break' so it has to be filled, since you're filling it you might as well set it.
3. Spend your entire day/week setting endcaps. (this is basically it)
4. Give some to your TMs to set whenever, at close, midday, etc.
5. Do what you can, let it build up, and at the end of the week when they are freaking out because TWT isn't 95%+ you can be like 'oh, my bad'.
6. Plan, partner, beg, anything to get help.
Don't ask why you're not getting the hours to complete your workload because then you're not owning your area, you're small scope, playing the victim, etc. You just have to get it done.
Don't question why they provide the SL team with enough hours to get the adjacencies and tables completed, or the POG team with hours when they were doing the SP (where did the hours go?!) because then you're keeping score.
Most importantly, DO NOT - I repeat - DO NOT go to your ETL/STL with a detailed breakdown of the length of time required to get your workload complete. Math confuses them. If you have 90 hours worth of sales planners, you being scheduled 40 hours (with 8 of those being during midday so no tasks, 8 for closing so no tasks, 8 on a weekend so no tasks, and we will round low and say 4 to cover breaks, FDC, huddles, etc., and we won't allocate any to CAFs or zone because well just because), 0 to 1 TM to use for roughly 3-4 hours every other day, they don't see how the numbers don't fit together.
edit - Learn which are CF, skip on backerpaper/signing, adjust the layout for speed (pegs vs. shelves), etc., minimize your walking, collecting all shelves, pegs, tools, etc at once.
Ignore the tape measure, eyeball the shelves.
Stop moving one that's currently set on the front to the back just because it says so on the new rotation, flip that part of the label if they are anal or get a different one, etc.
If you notice most of the time the company will have little changes in the basic layout of the endcap, for example, SP on X1 calls for 3 shelves (12 inches apart) and pegs at 66 on E, U, CC. Next rotation this changes to a new SP and the layout is roughly the same - 3 shelves and pegs, etc. It's not always like this but paying attention to this can save you a ton of time.
Use the adjacency and plan out your spots, the company makes it easy for us this way.
