Be prepared!

Whatever action you decide to take, the better prepared you are, the more likely it is that you will get what you want. There are a number of simple steps you can take to improve your case:

Keep a discrimination diary. Write down the date, time, what happened, who was involved and whether there were any witnesses. If you think they’ll be sympathetic, ask the witnesses to make a note of these details.
Keep a copy of any emails, memos or text messages that show what’s been happening.
Try to find a copy of your employment contract, and any employment policies and procedures of your organisation, particularly the grievance procedure (these might be set out in a staff handbook). Together, your employment contract and your employer’s policies set out your rights and obligations at work (these are usually called your ‘terms and conditions of employment’). You might need these to help show how you have been discriminated against.
And if you decide to raise a grievance, you’ll need to follow the procedure set out by your employer.
Think about the result you want. For example, do you want the person discriminating against you to stop but to keep working for your current employer? Do you want a decision, such as being turned down for a promotion, to be changed? Do you want your job back if you think you have been sacked because of discrimination, or do you want compensation for loss of wages, other benefits, or injury to your feelings? Or do you just want an apology?
In an ideal world, you should get legal advice about your rights and options, and legal help with whatever course of action you decide to take. If you end up bringing a claim, you should also get someone to represent you at the tribunal. See Get advice!.
