Not necessarily, as a child I was on a single injection of fast and slow insulins in the morning and at night but the regime depended on fixed amounts of food at fixed times of day so not sure it would be any easier. (This was before glucometers were invented so my control would have been much worse than that of today's diabetics.)
I would agree that injecting takes almost no time but doing a blood test before meals is harder work.
@mushed0 what is the health care like in your country? Do you get free diabetic supplies such as continuous glucose monitors? Do workers have any rights to do with health conditions? Unions?
