A question for you

An unusual image on many levels. Would Superman earn the same as Wonderwoman if they were both employed as superheroes by the same company - and would Superman do anything about it if he earned less? 

• University caretakers and maintenance staff got together and claimed sex discrimination after calculating their hourly rate was less than women on the same pay scale.
• Snooker referee, Michaela Tabb raised a grievance after not receiving a bonus from World Snooker Ltd and believed this was because she was a woman. The grievance was not upheld, Michaela resigned and claimed sex discrimination.
• Sienna Miller joined a number of female actors in speaking out for being paid less than male actors and of sexism in the industry. Sienna chose to turn down a role rather than accept an offer of being paid less than her male co-star.

People are often reluctant to speak out as they fear possible reprisals. Not Charlotte Proudman who made a LinkedIn comment public that she received from a male solicitor.  

What would you do?

PS  We reckon Superman would call his union rep.
