Contracts can be negotiable and many can be improved upon in some way. If you sign without negotiating you could be leaving benefits (money, vacation time, etc.) on the table.
William Roth created the Roth IRA in 1997 as a tax-free retirement investment. This investment will grow tax-free and can’t be taken out until you have reached 59 1/2 years of age. There are no RMDs (Required Minimum Distribution), so you can wait and let that money keep growing, even after you reach the minimum age to start taking money out. If you do this, you can keep making contributions up until 70 1/2 years old.
