I left to go on maternity leave in march doing 36 hours a week on days however my employer has said that I must do nights. Do they have the right to do this or are my rights being infringed. I am due back in December. I am a nurse in a care home.
Ive just returned to work after a years maternity leave. I'm not sure if this helps but for the first six months they have to keep your role open for you to return to. After six months they are only obligated to offer you a job of the same level and pay. It does not have to be your previous role. Since you will have been off longer than six months, maybe they are entitled, but someone with an employment law background maybe able to advise you better.
You need to read the 'statement of employment particulars' which your employer was legally obliged to provide you with within two months of commencing employment. If it states that your hours are, for example, "from 0800 to 1600" it probably unlikely that your employer could lawfully switch you to night shifts without your consent. However if it states that your hours are "as may be required by the employer" you might find it hard to argue against the change.
