Many thanks for your patience. First of all you need to check your employment contract to see if it says whether the employer is allowed to do what they are proposing to. There could be a specific clause which says that when someone is off sick they could collect these, for example if someone else may need to use them in your absence.
In the absence of such a clause, taking these items off you could amount to discrimination, if you are suffering from a disability. For this you must be able to satisfy certain criteria and it is not limited to physical conditions only, for example depression can also be a disability if it meets the criteria. So if you are being treated detrimentally because of a disability, that would amount to discrimination by the employer which is unlawful.
Finally, even if you are not classified as being disabled, being treated in this way could amount to a breach of the implied term of trust and confidence which exists in every employment relationship. This could allow you to resign and claim constructive dismissal if necessary, subject to you having at least 2 years continuous service with the employer.
This is your basic legal position. I have more detailed advice for you in terms of the law on disability and how to establish if you are disabled, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
