Hi, am writing on behalf of my sister. She has been working 3 days a week for a company since August. A couple of weeks' ago the Director said they wanted her to go full-time as they had underestimated how much work they had. She said she wasn't keen as she is a single mother, has 2 young children and would have difficulty getting them picked up from school 5 days a week and looked after in the holidays (her in-laws help while she's doing her 3 days, ex-H hasn't seen the children for 5 months, his choice and a whole other thread!) She said she would be prepared to work an extra 2 mornings, but they said this was not enough, they want 5 days. They went away to think it over. Today, she was told they will have to let her go. Can they do this as the job was advertised as 3 days a week and she wouldn't have applied for it if it were full-time? Seems very unfair, or does she have no rights as she hasn't been there very long? She is gutted, doesn't know what to do as she will lose tax credits, etc. Any advice much appreciated!
