Seniority of the jobs filed
The government assigns each job one of four wage levels. A higher level means a higher legal minimum.
What these numbers are
- They are wages Spark Therapeutics, Inc. attested to on Labor Condition Applications (Form ETA-9035), not paychecks. Bonuses and stock are not included.
- A filing is not a visa or a hire. One filing can cover several positions, and some are later withdrawn. Wage figures use certified filings only.
- The prevailing wage is the minimum the employer must pay for that job in that area, set from government wage surveys.
