An Employee Invite cannot be sent without a rate.
TiM encourages best practices between employers and employees. According to the New York Department of Labor and the NY Wage Theft Prevention Act (WTPA), employees must be notified of their wage at the time of hire: "the WTPA requires employers to give a written notice to each new hire. The notice must include: Rate or rates of pay, including overtime rate of pay (if it applies) − How the employee is paid – by the hour, shift, day*, week, commission, etc.". (There is also a Wage Theft Prevention Act in California.)
An Employee Invite serves as this written notice that an employer has notified the employee of their wage at the time of hire. Therefore, Employee Invites cannot be sent without rate information.
* Day rates cannot be entered in TiM. They must be broken down into an hourly. The only exception is for employees who are members of the DGA, SAG-AFTRA, and Local 800 because their collective bargaining agreement rate is high enough above minimum wage.
