Was this rude ?

[HowdidImanagetohavetwoaccountaandthenloseboth]

I am a tutor teaching a hobby . I also belong to a hobby group similar to what I teach .
some months ago , after some of my work was admired at a group session I offered to run a day course at the group . This was readily accepted , a date sorted and terms agreed verbally . I started preparing for it .
Last week I was sent the contract forms ( all taught sessions are paid by the group ,) for that event.I was intending to hand them in in person yesterday .

Yesterday, the group postponed due to the weather but the full programme for the year was sent out in a email to everyone with my day missing .
I was confused and politely enquired , was this a mistake ?
The email back said No it was intentional and instead they wanted me to do a 20 minute slot at a shared session at another time of the year .
I cannot teach what I proposed in 20 minutes and was not asked about my availability. The original session is unfilled . So it’s not as though something has to give .

I was rather taken aback at the change so late in the day and without consulting me , I sent a curt email back .

instead of an apology , I received another email this morning acknowledging the change and asking me to do another task for the group!

Am I being sensitive or is this rude ?

I wouldn't say it's rude, more thoughtless and disorganised, you are not being unreasonable to be annoyed

I wouldn't be offering them my services any more

I think it is rude that you didn't receive an apology - or even a heads up before the timetable went out.

It’s rude, it’s dismissive and it’s bloody ungrateful. I’d reply to their request to do the other task with a simple ‘No thank you’ and wouldn’t offer again.

Was this a voluntary session or were you to be paid for it? Either way, yes it's rude, and I there would be no session later in the year available.

It's rude, yes. I would tell them you're not available to work with them in future.

@GoldDuster I was to be paid for it albeit at less than I would usually charge at my choice .

I think context would help - what activity is it?!

If they offer you work in the future, decline.

This.

Say you are no longer able to teach the session as the new terms are unsuitable for the activity.
