It can be incredibly challenging to maintain a balance between the number of tasks at hand and the available workforce. The situation you described, with a portion of the employees being assigned to fieldwork while still having to handle desk-related responsibilities, can indeed lead to physical and mental strain, as well as a decline in creativity.
By actively communicating your concerns and proposing solutions, you increase the chances of finding a resolution that benefits both you and your colleagues.
That's right my friend, will I be able to change my character so that I can accept my job under any circumstances by being calm and patient? Who knows! but I'll keep trying to improve it.
Thank you very much for your comments and motivation.
