They get OT, ten days paid time off, all six major holidays and then some. I also pay half of their healthcare. I didn't see your link so I can't compare.
I have to say that you seem like a really good employer. Sorry about the missing link. Here is another (couldn't find the first),
https://www.expatistan.com/cost-of-living/portlandThe benefits I had before I retired which you didn't mention offering were; earned sick leave at the rate of one day per month with unlimited accumulation (I used mine to cover state mandated family leave when my wife was ill), increasing vacation time with longevity, topping out at 4 weeks per year with an accumulated max of 350 hours, fully paid retirement benefits with the choice of a guaranteed annuity for life, a one time payout, or some combination thereof. Full-family quality medical coverage was paid at about 80% give or take.
I worked in education for a public employer. Because of union responsibilities and associated political involvement at both the state and national level, my employer allowed unlimited time off, all of which was reimbursed by the union with the exception of employer (HR) requested assistance, which my employer covered. I represented over 1,000 employees give or take. As you might imagine, I spent a lot of time, both on the clock and off helping my employer and fellow employees work though difficult HR related situations. This was challenging work. Legally my mandate was to represent the employee. Practically, I was a mediator. Actually, I was a trained professional mediator.
In no way do I want to leave any impression that my union work was a burden. I saw it as a service, both to my employer and to my fellow employees.
Advice: If you are not running a union shop and don't want to, offer the same or better compensation than union shops do. Precision Castparts in Oregon has managed to pull this off successfully for a very long time.
