The discount you get depends on the arrangements your employer has made with Workit, so the benefit differs per organisation. The benefit is often part of a tax scheme, which means you pay less net than the gross price of the subscription.
Want to know exactly what your benefit is? Log in with your employer's code to see the amount that applies to you. Unsure about the scheme itself (for example how much your employer contributes)? Ask your employer, as they decide the amount of the benefit.
