I am a software engineer and speaking at an opensource software conference. Although the conference is paying the flight and hotel expenses, I still need to pay for the visa fee.
Also, I wish to attend one of the workshops at the conference (for which I need to pay). I presented at this conference last year as well but my employer refused to pay for the workshop as they believed that the topic of the workshop was not relevant to them (with which I do not agree).
So, while they are fine with paying for the visa application fee, they don't want to pay for the workshop. How do I convince them to support me for both, I feel I am asking them for too much.
And finally, when I am speaking at these conferences, all the attendees get to know about my employer, which is a good thing for them (my employer). So, is it wrong if instead of using my leaves to attend the conference, I ask them to treat as work rather than vacation?
