Make sure you file the claims. The law provides that you are to be compensated legally.
If you get fired as retaliation for making legal wage claims, then hire an employment attorney in Libertyville.
You should consult with an employment attorney immediately. The law in Illinois is unclear as to whether you would be able to file a retaliatory discharge claim if fired for filing Wage Act complaints.
Get in touch with a lawyer asap. You likely have claims under the Illinois Wage Payment Act, which gives you certain rights regarding the payment of bonuses, wages, etc. You have a right to file these claims. Perhaps filing a lawsuit, rather than claims with various agencies, etc., is the better route as you could then combine all the violations into one lawsuit.
