Smw9927, I shall start right from the very beginning, which may make this rather long but if you know the whole story it should make more sense.
when the job was advertised and I applied 4 and a half years ago it was advertised as a part time position. When I went to the interview I was told it was actually a jobshare position. This was fine I didn't have a problem with that. I got the job and was sent a letter stating that I got the job of part time XXX (job share).
Over a 3 week rota I worked
Monday 4 hours, Wednesday 4 hours and Friday 6 hours. This amounted to 14 hours working and I was paid for 15 hours. the extra 1 hour pay was put towards the saturday shift that I worked once every 6 weeks. So over the 6 weeks I was paid 6 hours extra (1 a week) to pay for the saturday.
Q1, over 6 weeks I worked the same days and hours.
The other girl worked all day Tuesday 9-5, Wednesday9-5 and Friday 9-5 and also did one Saturday in 6. She would have worked 21 hours a week but been paid 22 hours again to pay for her saturday shift.
2 years ago the other girl took up an additional post so she dropped her Tuesday shift and her Saturday and I picked them up. She still worked all day Wednesday and Friday but no Saturday.
I then worked Monday 4 hours, Tuesday 6 and a half hours, Wednesday 4 hours and Friday 6 hours. This amounts to 20 hours 30 minutes. I was paid for 22 hours every week, the extra 1 hour 30 minutes going towards the two saturday shifts that I now did. I would work 6 hours on one Saturday and 3 hours on the second Saturday.
Q1, Again over the 6 weeks I worked the same days and hours every week.
Q3, this also answers number 3 as I picked up the other girls hours so it was a change in hours for me.
Incidently although I had to fill in a form for the payroll department asking them to pay me for 22 hours per week I was never sent a formal letter saying "your hours have now changed"
At the end of September my Jobsharer left. I asked if I could work 3 full days and the new person could do the other hours. My line manager said this would be fine and asked me to write down which days I would do and which hours and also to write down the days and hours that the new person would do.
I suggested that the new person work my original hours of monday, wednesday and Friday plus one saturday in 6. and I would do my old job sharers hours of Tuesday, Wednesday and Friday and one Saturday in 6. I put down that I would do 9.15-5, so that I can drop of my dd at school on the way to work. My line manager approved this and it was sent up to the big boss. She also approved this and it was then as far as we know went to the staffing department and the job for the new person was advertised.
The only problem is that nobody checked the hours added up. To do the hours I suggested I need to lose some pay and this should have been transfered to the new persons job. I didn't realise this at the time. The reason for this is because my old jobsharer never started at 9am she was always in by 9.15 which is what I thought her hours were and is why I suggested a 9.15 start for myself.
The new job was advertised and a person has now been employed but there has been a huge mess up. Apparently because it's a job share position we should NOT both be working one saturday in 6 each we should be sharing the one in six and therefore doing one each every 12 weeks.
It wasn't advertised as a job share position and the new persons letter states part time position.
She has been given a contract which says that she is to work 15 hours per week. It doesn't mention Saturday shifts at all.
It would seem that the Staffing department think I work 22 hours Monday to Friday. I'm a bit worried about this because our work pay scales were upgraded earlier this year. When it went through everyone was sent a form to sign. I have realised that the letter that accompanies this says that "your hours of work are 22 per week" I didn't pick up on this at the time and I signed the form because I have always been paid for 22 hours per week and so thought this was correct.
I feel that since my line manageer agreed to the hours suggested as did the BIG boss that they should really stand by this. Someone somewhere should have checked the hours added up correctly. But I'm not sure if legally I can insist on them honouring the hours agreed.
If you have managed to get to the end of this and make sense of it, thank you.
And I welcome any advice.
