The "No Tax Breaks for Union Busting Act" aims to eliminate tax benefits for employers who try to influence their employees' decisions regarding labor organizations and collective bargaining. The legislation seeks to protect workers' rights to organize and engage in collective actions without undue employer influence, ensuring that employees can freely choose their representation. Key provisions of the bill include a modification to the Internal Revenue Code that would deny tax deductions for expenses incurred by employers attempting to sway employee opinions about unions.
