I have worked as a contractor/consultant most of my career. I’m starting a “permanent” job in January for the first time in a very long time. I also work with tons of other contractors/consultants.
I would say at a minimum of around 1.5x her actual reimbursement rate. You have to also figure in there’s likely no more sick pay, vacation, holiday pay, 401k match, etc. etc. In my opinion, those all need to be factored.
For example, if someone makes $200k/yr, I would not consider their actual hourly rate to be $200k/52weeks/40hrs. If they get 4 weeks vacation, 5 sick days, and 10 paid holidays, I would consider their hourly rate to be $200k/45weeks/40 hrs.
It also needs to be known how many hours they will be working and whether it will be straight time or 1.5x OT (if OT is available).
My last two contracting agencies I’ve also been able to work in referral bonuses of anywhere from 1% pay increase for each referral or $750-$1000 bonus for each referral. This has been huge when I interview with the agency first for a position (before the company) and I tell them that in past projects i’ve been able to pull on 5-10 more people onto the staffing agency. They see this as a huge incentive and then push harder and also had less of a markup on my wage so they could get my foot in the door.
