During Treatment

Working During Breast cancer

Posted by Sara Liyanage on 04 October 2017

Some breast cancer patients take a complete break from work to get through the treatment, whilst others find that working throughout treatment is a welcome distraction. Sometimes extended time off work isn’t even an option. Whichever of these situations you find yourself in, there are questions that you probably have, and rights you may not know you have. We have done a bit of research and put together a list of what we think are the main issues, together with some super helpful links. BUT this is not legal advice and so you must ALWAYS contact a professional if you have questions about your rights – this section is just a starting point for you.

The main issues which arise during breast cancer treatment in relation to working are:

1. What, how, when do I tell my employer that I have been diagnosed with breast cancer?

You don’t have to tell your employer that you have cancer. But you are protected by certain laws when you have been diagnosed with cancer and this means that your employer cannot discriminate against you because you have cancer. If your employer doesn’t know that you have cancer then they may not be able to help you in a accordance with your rights under the law.

Some employers have policies in place to help their employees who have been diagnosed with cancer. These may include time off for appointments, support with your work load and providing someone to talk to about your diagnosis. It is worth asking your employer if they have any such policies in place. And if you don’t tell your employer about your diagnosis then you won’t know about any such policies that may help you.

Sometimes it just makes life a bit easier by telling your employer so you can discuss how you want to fit work in around your treatment, whether you want to carry on as normal as possible or whether you need time off. Your employer has to respect your wishes as to whether your co-workers are told about your diagnosis.

2. Am I allowed time off for treatment?

The law requires your employer to make what is called “reasonable adjustments to your work place and their working practices”. This means that they are required to allow you reasonable time off for your medical appointments, treatment and if your treatment makes you ill.

3. Will I get paid if I take time off for treatment?

This depends on your employment contract. So ask your employer for a copy of your contract if you don’t have a copy. You will usually be entitled to Statutory Sick Pay. You may be entitled to other pay (Occupational Sick Pay or Company Sick Pay) depending on your contract so it is a good idea to discuss this with your employer. You may be entitled to some benefits if you take time off work. The ‘helpful resources and more information’ link at the end of this section directs you to Macmillan’s advice about benefits.

4. When do I need to return to work after treatment?

The amount of time that you take off work will depend on your treatment, your recovery and your own personal discussions with your employer.

5. Will my employer keep my job for me until I am ready to return to work?

The law requires your employer to not discriminate against you because you have cancer. This means that your employer cannot dismiss you or make you redundant for a reason relating to your cancer or treatment.

6. What if I need to reduce my hours when I go back to work?

The reasonable adjustments that your employer is required to make for you under the law also applies to when you return to work. You can ask your employer for a phased return to work so that you go back to work gradually. You can also discuss with your employer about any changes that you need to make on a long term basis, such as less hours or a flexible working pattern. Your employer is required to consider this under the law.

Going back to work

Career Coaching Workbook for £9.99 Working With Cancer have developed this workbook for cancer survivors and cancer carers. It has been designed for you to work through with a WWC coach or to use independently. For people with cancer: it has been designed for anyone with cancer including those on ‘watch and wait’ regimes or with treatable but not curable cancer. What you all have in common is a desire to carry on working, explore opportunities and take on new challenges. For cancer carers: you may have spent the last few months or years juggling work and caring responsibilities, possibly undertaking work that wasn’t your first choice but which at least paid some of the bills. Now, with your caring responsibilities at an end, you may want to do something different, perhaps more interesting or better paid. Where to start looking and how?
