I have been given a hospital appointment this week under a referral, and it clashes with the day I am supposed to go into the office to meet my line manager in person for the first time. I have been in my job for 3 months and I'm still in probation.
Half of me thinks that I should cancel it to as it would be unprofessional to have to rearrange meeting my manager (visiting them involves an overnight stay on my end - they live near the office), and with me being in probation I'm obviously conscious of making a good impression. However, the other half of me thinks that hospital appointments should take priority above anything else, as they are hard to rearrange and difficult to get in the first place.
