How to deal with discrimination at the workplace?
You are working in a manufacturing plant with high velocity fans & wearing fabric headgear? Normally companies have dress code requirements for production facilities for safety purposes. Maybe you should go to HR and ask for the dress code policy. Develop a thicker skin, rarely do discrimination cases merit any real cash. It has to be pervasive discrimination before anyone gets too excited about it.
What would you do if you found out that a recently hired co-worker, holding the same responsibilities you have
Well, first off, ask yourself why, and think about what factors might be causing it. Is it possible they have some qualification or experience you don't have? Maybe they are just a better bargainer when it comes to wages? Perhaps they are related to the company CEO? If you have considered all legitimate possibilities, it could be that something illegal is occurring ~ such as discrimination. I would definitely ask around (discreetly) and find out as much as I could before proceeding. My next step would be to ask my union for legal advice about my rights and feedback about others who have had a similar experience. If that option is not available, you could perhaps approach the HR people or your boss and request a raise. You could say that in the competitive marketplace of today, your salary is simply not keeping pace and you'd like to apply for a rise. This is all assuming you would get a rise if you requested it, or pushed for it. If you don't think the boss would come to the party, it might be time to find a new job where your skills are better valued. And of course, make sure you start the bidding a bit higher than last time! Best wishes :-)
