Last thursday I had to go to another emergency doctors appointment, my works rules are phone 2 hours minimum before your shift so they can arrange cover. I gave them 4 hours notice and not one single manager bothered to tell my department so they could arrange cover leading to a fellow colleague not leaving til 11pm. Come saturday my manager had heard about this and started getting funny with me saying im starting to look suspicious as im always off of work and this got on my nerves a fair bit! Later that day he brang out the new rota and weeks ago he agreed to give me holiday for my hospital appointment with the specialist. But nope, didnt put me down for holiday but gave the person i share the shift with holiday and i had to agree to a shift swap. Today was the day of the shift swap and i had been very bad since yesterday evening, but because it wasnt my shift i had to go in. By the time i got in i instantly found another manager and poured my eyes out crying and she told me to definitely go home but thanked me for trying and reassured me she'd have a word with my manager. But im still scared to death im gunna get screamed at again because he doesnt bother trying to understand what im actually going through and how unpredictable it can be.
I really do fear losing my job. Help?
