Strong, Serious, Work Ethic

My typology question for the day. What type tends to have a strong, serious, no nonsense work ethic? I find myself getting irritated with people who seem to have lackluster work ethic compared to mine. I have been called to serious/intense and told to “calm down” but I don’t believe in “calming down”, especially when it comes to work. I’ve been considered a workaholic.

Knowing enough about this typology system, I know this has been given to LSE or LSI. Someone recently considered LSE for me as well which was a first due to me not liking being rushed. However, between LSE and LSI, I’m wanting to know the distinct differences between the two when it comes to “workaholic” tendencies or work ethic overall. Thank you in advance.
