Sure.
As long as the offer is at least the minimum, the employer can offer anything,
Then it's up to the worker if agree, skip or try to negotiate.
After a new worker have shown how good he work, a contracts can be renegotiated IF BOTH parts agree. A clever employer want to keep GOOD workers satisfied, but some employers aren't clever...
((Back before I started own business, I agreed to low start salaries to get CHANCE to show how good I work.
At my first employment I started at average and got the salary raised to a bit over the double in 3 years.
The second employer was bad, so close before I quit I did show him how good I COULD have worked
The third asked if I could agree to low salary because I had no experience of such business. I said I agree to LOWER than that
2 years later I had got my salary more than doubled, so i stayed there until I started own business.))
So it's possible to negotiate at least if the business is small enough to the negotiations are made with the top boss or owner so they realy bother how good the workers get things done. The clever ones agree to raise your salary IF you work obviously better than expected for your salary...
