Does there need to be much complicated about that?
Seems like they could simply pay your an hourly rate for your time spent working, with no benefits.
Also - since your rate is directly billable to clients, if you wanted to work an extra hours at 1.5x your rate for overtime, your employer should be able to simply factor that into your overall billable rate to their clients.
I’ve been contract for around the last decade or so (oil & gas) and I have found a LOT of flexibility for negotiating contracts. I’ve worked salary, day rate, straight time (including straight time after 40) and hourly with OT after 40.
I recently started a new position this year and the negotiating process was insanely laborious. We went through a huge gauntlet, looking at all the standard options above..
I had a great job I was currently working and they were desperate so I had a ton of negotiating power. Also - this was a job full of hundreds of contractors, and my agency was “new” and I was their first person on site, so they had major incentive to make it work.
Others on site were only getting time and a half after 45 hrs, however I negotiated time and a half after 40 (although my agency can only bill for it after 45). I also managed to get $15/hr more than their peak salary range. My contracting agency reduced their markup to get me on board and get their foot in the door (I’ve since brought on two more people through their agency, they raise my hourly rate with each one as a referral bonus). I typically work 50-55 hrs/wk year round, so it’s worthwhile.
Anyways - just pointing out that there are tons of different options.. I think that hourly w/ time and a half would be your best bet if needed.
I think that a reduced salary year round would be a stretch and hard to justify for accounting purposes..
Million different ways to skin a cat and come up with the number you want, just don’t lose sight of that.. You can tackle things a million different ways but ultimately want to ensure your required take home pay is where you want it, regardless of the pay structure.
