Ha ha ha, NO. No No NO!
@Getmystuffsorted you should not be having to swap your days to go to to pre-natal appointments. As has been said you are entitled to go in works time. It would be more convenient for your employer of course, if you switched days, but why should you? If you worked 5 days (Mon-Fri) you'd be going in your working hours -so what's their problem?
Reminds me of a long time ago when I was working in this certain job in the early 2000s, and I worked 3 days a week (DC were primary school age,) and my employer wanted me to go on a 2-year long course (part time - 1 day a week.) (To improve my knowledge of the job and get a qualification in it, even though I was only doing the bloody job for the money!🙄) They had pushed a few people onto it actually! They were paying for the training, and were actually offended and annoyed if people said no because it was freeeee. All very well doing higher education/training courses if it's something you are interested in. What I was doing (at the time) was boring. Like hell did I want to waste my free time studying it further.
Anyway, they wanted me to go onto this 2-year, 1 day a week course, (HNC I think it was,) and they expected me to go on a Monday, when I worked Tuesday, Wednesday, and Friday! I said 'no, I'm not going on my day off. Julie and Carol go in works time, so why shouldn't I? If you want me to go, I will change my work days to Monday, Tuesday, and Wednesday, go to the course on Monday and come in Tuesday and Wednesday.' They said 'don't be silly, Julie and Carol can't go in their own time because they're full time - 9-5 Monday to Friday, they have no choice but to go in works time. YOU can go on one of your days off.'
No matter how I tried to resist and explain, they wouldn't have it. I said 'why should I go in MY time, on a day where I am not paid when everyone else goes in works time, and gets paid to go? If the course day was a Saturday, and Julie and Carol work Monday, Tuesday, Wednesday, Thursday, and Friday, do you think they would be happy to go then? All day Saturday? In their own time? A day that they're not paid for.'
They just did not get it. Just insisted I went on one of my 2 days off. I dug my heels in and refused to do it. They bitched and moaned and said I was 'ungrateful' but I said 'no. It's either on one of my 3 work days or not at all.'
