Research
My searches here on Workplace didn't answer my question because the focus was, for example, on family reasons or if there was any doubt about the necessity of the business trip. The most similar question is this, the worries and fears are comparable. Nevertheless, I would like to clarify further questions for my situation.
Context
I have been working very happily in a company as a product manager in purchasing for 2.5 years. It's not written down in my employment contract, but the job description lists visiting trade fairs and suppliers as a sideline job.
When I started, there were no business trips due to the global Corona pandemic. After travel restrictions were lifted worldwide, trips, trade fairs and supplier visits increased again. So far only within Europe. The trade fair and supplier visit themselves are fine. I have found that I struggle with problems when traveling long distance. The greater the time difference and distance from home, the worse the symptoms become. When traveling long distances, I suffer from anxiety and panic attacks, especially at night, which prevent me from getting a restful sleep. Combined with the time difference, this degrades my physical and mental fitness throughout the day to an unworkable level. It is unthinkable to have a professional appearance with suppliers if you are completely tired and exhausted. Potential business trips are usually shorter than I would need to acclimate to the time difference, but the sleep problems persist.
On private trips it helps a lot if my significant other accompanies me. He can calm me down with the problems. However, his presence is obvious not an option for business trips. I don't think it's right to take medication etc. just to be able to go on a business trip.
There have been no long-distance business trips yet. But just the thought of a trip like this, without anything concrete currently planned, leads to stress and discomfort. However, it is only a matter of time before a long-distance business trip takes place.
My work performance so far has been impeccable, even without long-distance business travel, and my employer has been very happy with me from the start. Based on my performance, I was recently appointed as a team leader for a specific product area.
Furthermore, I do not have and do not want a medical certificate that would certify that I am unfit to travel. The legal situation in Germany is that the employer has the so-called “right of direction” with which he can order a business trip. I am not looking for a legal perspective on the situation.
Thoughts
I am aware that visiting trade fairs and suppliers is part of this job. However, I don't want to burn bridges with my employer or worsen my future prospects. I have already thought about that I want to describe my problem transparently to my superiors. I am still concerned that stopping long-distance business trips will not meet the requirements of being a product manager in purchasing in the long term. Since refusing or rejecting business trips can be problematic in terms of fulfilling the employment relationship or my job, I considered whether an internal change to a position without business trips should be discussed. However, there is currently no such open call for tenders. There may not be any suitable internal position that my employer is willing or able to offer. I might overthink the situation.
Questions
How can I professionally and politely communicate to my employer that I no longer want to take part in long-distance business trips due to these problems?
In general, does it make sense to directly present suggestions for an internal change of position in the same conversation due to the requirements for being a product manager?
