We used to have £500 a year, but that was cut in the last couple of years. (In fact I know my current dept used to have £1k a year allowance each pre-covid)
I'm on probation and one of my requirements is to present my work at international level conferences, so it now feels like pay up personally or face arguing that condition when we're already facing mass redundancies, or defend my inability to get external funders to pay my costs.
I had to pull out of one conference that would have been great at the last minute when cuts were confirmed as I just couldn't cover the cost myself, which was embarrassing and damaging.
I managed to get some funds to go to a conference this summer but just to cover one day's attendance, no travel or accomdation. 14 hour day for a 20 minute talk, I missed all the networking as I had to leave as soon as the last talk finished and my morning train was cancelled so I missed the arrival drinks etc, it was miserable.
Over the years I've had a combination of paying it all myself, scraping together bits of cash from various pots, paying some of the costs myself, having a personal research allowance, to a couple of random fully funded conferences at luxury venues which included free day trips and expensive gift bags.
I was chatting to DH the other week about the fact it used to be normal to just go to conferences you weren't speaking at to keep up with the field, now not only is that rare but I've noticed more and more that speakers are either PhD students or Profs - we guessed noone else has the time or funding to do the research and the travel now.
Its a big shift in the culture, and not a good one.
